How to Build an 8-Core Gaming PC from Cheap Server Parts

Kannon Yamada 23-03-2016

Want a beefed-up gaming or video-editing PC with dual Intel Xeon processors for under $200? The parts are out there, but finding and putting them together could prove difficult. This article covers what parts to look out for, and where to find disused server hardware that will make for an excellent gaming platform or workstation.


If you’re looking for something less powerful, then check out our guide on how to build your own pc How To Build Your Own PC It's very gratifying to build your own PC; as well as intimidating. But the process itself is actually quite simple. We'll walk you through everything you need to know. Read More .

Unfortunately, there are some caveats. First, these are older server processors, which means they need older motherboards and special RAM. While cheap, they’ve likely suffered years of heavy use, leading to wear and tear. Their long-term reliability might not be worthwhile. Second, if you want performance comparable to today’s desktop systems, you’ll need to use a dual-CPU motherboard (which isn’t the same as a dual-core CPU).

Linus, from Linus’s TechTips, created a video on the subject:

While Linus uses a grittier approach (he doesn’t even bother with a case), I have some additional tips on building your own rig from moldering, throw-away server components.

The DIY Junkatron Parts

The easiest method of rolling your own PC from server parts is to buy an entire server. An entire server offers 100% part compatibility (the biggest concern and issue), as well as overall cheaper cost. On the downside, shipping can be really expensive, and it’ll restrict your choice of graphics card. If any component fails, the server might also require proprietary replacement components. Most users, without access to a disused server, will probably end up buying the parts à la carte.


The five most important components — in order of importance — are the motherboard, the case, the RAM, the power supply, and the Central Processing Unit (CPU). While all of these parts are important to performance and inter-component compatibility, I list the CPU last because once you’ve picked the other components, the CPU becomes more of an afterthought.

The graphics card is the only part we don’t tackle, as server machines typically don’t have discrete cards – but you can read about how to pick the best GPU How To Choose The Right PC Video Card [Technology Explained] Read More for your system, then purchase either new or used, using the notes in this guide that restrict your choice (such as motherboard and case size). Keep in mind that a decent GPU will cost more than the entire system. Something along the lines of a NVIDIA GTX 750Ti is probably the most suitable option, since it’s power efficient, inexpensive, and easy to fit in most cases, though you could also go with an AMD Radeon R7 360 and not lose any sleep over it.

The Motherboard

Selecting the right motherboard determines the rest of your build, including the case, power supply, RAM, and the CPU. The primary advantage of choosing an older server motherboard is that it may include two CPU sockets, instead of the standard single socket on an ATX desktop motherboard. Don’t confuse the CPU count with the number of processor cores. Server motherboards can offer two physical processors which boosts performance in games using the upcoming DirectX 12 (DX12) Application Programming Interface (API), which more efficiently uses multiple processing cores. If DX12 or AMD’s Mantle is used in future games, an 8-core Intel system could provide performance on par with, or superior to, today’s latest two and four core processors.

However, before you pick a processor, you must first choose the motherboard, which determines the processor socket compatibility. As far as manufacturers go, Supermicro is highly recommended – they tend to offer better operating system compatibility and often work with Linux and Windows 7. Many are even upgradeable to Windows 10. However, there’s a lot of Supermicro boards out there, with differing CPU sockets. A CPU socket determines the kind of processor that you can use.


CPU Sockets: The two most suitable sockets include  the Core 2 Duo generation of LGA771 socket and the Nehalem-generation of LGA1366 sockets. LGA771 uses DDR2 RAM or FB-DIMM RAM, whereas LGA1366 uses DDR3. Both LGA771 and LGA1366 come in dual-socket configurations. Pictured below is a dual-socket LGA1366 E-ATX Supermicro motherboard:

lga1366 dual socket supermicro motherboard

PCIe speeds: Most LGA771 and LGA1366 sockets include support for x8 and x16 PCIe speeds. However, the motherboards aren’t designed to accommodate a full-length PCIe GPU. This requires that users either find short-length PCIe GPUs or that they measure the motherboard to determine whether or not their GPU of choice will fit inside of the board.

If you can find a motherboard with the CPUs still attached, also make sure the heatsink-fan combination is included. Finding server-compatible heatsinks can be expensive.


I highly recommend staying away from motherboards pulled from pre-built units. These include any Dell PowerEdge, HP Proliant, or other similar server builds that rely on proprietary components — unless you’re buying the complete server unit, including the case and power supply.

Here’s a quick checklist of things:

  • Measure the motherboard to make sure it fits in your case.
  • Try to buy a motherboard sold alongside a CPU and RAM, which allows you to test whether or not the board works, without buying additional processors and RAM. You don’t need to take this step if you know what you’re doing.
  • Not all server motherboards are E-ATX in form. Supermicro also sells a number of ATX motherboards, which should fit into most ATX cases.
  • Supermicro provides a list of their server motherboards. Look for ATX form factor boards with LGA1366 or LGA771 sockets.

The Case

I list the case second because many motherboards can come in irregular form factors, which include Extended ATX (E-ATX). Brand new E-ATX cases, unfortunately, can be expensive, and often offer no more PCIe slots than a regular ATX motherboard. That’s because E-ATX boards tend to run deeper, rather than wider, which is suitable for a server or workstation, but not for a gaming or video-editing machine. Fortunately, server motherboards come in both E-ATX and ATX form factors.

Here’s an example of an E-ATX case on Amazon:


eatx case amazon deep cool

It’s huge and primarily designed for squeezing in a large number of hard drives. I don’t recommend buying an E-ATX case, unless you already own a server motherboard: some E-ATX form-factor motherboards won’t even fit inside of an E-ATX case.

Why not pick from one of these top PC cases instead?


As mentioned earlier, the motherboard determines that kind of RAM that you’re using. Unfortunately, almost all DDR2 server motherboards require either ECC DDR2, ECC registered DDR2, or FB-DIMM RAM. FB-DIMM is a different form factor to DDR2 memory modules and this limits compatibility to special motherboards. Here’s an example of how DDR2 differs from an FB-DIMM stick:

ddr2 vs ddr2 fb-dimm

You’ll notice that they are not pin compatible. Therefore, it’s critical to pick the right RAM. An FB-DIMM stick of RAM won’t fit into a DDR2 socket; a DDR2-ECC stick will fit into a DDR2 socket, but it probably won’t work with the motherboard if it doesn’t support ECC memory.

While DDR2 RAM costs almost nothing, particularly for 1 or 2GB sticks, ECC and FB-DIMM memory are notoriously unreliable and have higher latencies than non-ECC RAM (which is bad). Above all other concerns, ECC RAM can be extremely finicky about what kind of motherboard it works with. The easiest method to guarantee compatibility is to purchase the motherboard with RAM. Alternatively, you can check the motherboard’s approved RAM compatibility list from the manufacturer’s website.

Keep the following tips in mind:

  • RAM must be used in pairs.
  • ECC DDR2 RAM is different from ECC registered DDR RAM. Most server boards use registered DDR2 and not just ECC, but it varies by motherboard.
  • ECC DDR2 RAM is not pin-compatible with FB-DIMM RAM. Check your motherboard for compatibility.
  • Don’t mix and match sticks of RAM.
  • DDR2 and FB-DIMM RAM is for LGA771 socketed motherboards.
  • DDR3 is for LGA1366 socketed motherboards.

A final note: DDR3 RAM is significantly easier to use as all DDR3 is the same form factor, regardless of its server capabilities. However, many server motherboards still require ECC memory, which can cost more than non-ECC RAM. Similarly, check the motherboard’s approved RAM compatibility list, before buying anything.

The Power Supply

Picking a power supply can also be a hassle. For those not in the know, read about picking the perfect power supply Power Supplies Explained: How To Pick The Perfect PSU For Your Computer Most geeks interested in buying new hardware or building a new system think first of the processor, graphics card and perhaps the hard drive. These components have the most impact on performance, so they are... Read More . Pay careful attention to the total wattage of your build and the number of CPU power pins required by the motherboard.


Dual socket motherboards require more power than single socket boards. Often the motherboard will have an 8-pin CPU power connector. This means that the power supply must also have an 8-pin (4+4), rather than a typical 4-pin CPU power connector, though you can buy an adapter cable. Regarding load capacity, most 600-watt power supplies will work for a dual processor build. For better stability, though, you might want to over-provision on wattage. Those old server boards can be extremely power hungry. You should also consider the power requirements of your graphics card. 6 Inch 4 Pin to 8 Pin EPS Power Adapter with LP4 - F/M - ATX to EPS Power Adapter (EPS48ADAP) 6 Inch 4 Pin to 8 Pin EPS Power Adapter with LP4 - F/M - ATX to EPS Power Adapter (EPS48ADAP) Buy Now On Amazon $8.57

If you have an old (and powerful) power supply on hand, you should consider reusing it: Can I reuse my old power supply? Can I Reuse My Old PC's Power Supply in a New Computer? Upgrading your PC but don't know if it's okay to use an old PSU? Here's what you need to know about using old power supply units. Read More

I recommend using eXtreme Outer Vision’s wattage calculator to determine whether or not your power supply can provide enough wattage.

The CPU and Heatsink-Fan

The CPU and heatsink-fan are both determined by the motherboard (how to mount a CPU heatsink How to Choose and Mount a CPU Fan: Everything You Need To Know Are you looking to mount a new CPU fan? Finding the right CPU fan requires a great deal of research. Not only do different fan sizes populate the market, a byzantine maze of CPU socket... Read More ). There are four kinds of processors available to LGA771 and LGA1366 sockets. These are:

  • Core: 65nm production process. LGA771 socket. It’s the slowest of the four architectures.
  • Penryn: 45nm die-shrink of Core. LGA771 socket.
  • Nehalem: New architecture based on a 45nm production process. LGA1366 socket.
  • Westmere: Die-shrink of Nehalem on a 32nm production process. LGA1366 socket. Westmere is the fastest.

The Penryn or Core architectures are cheaper. Even so, I’d argue that Westmere or Nehalem offer better bang-for-your-buck, as they use DDR3 RAM and the LGA1366 socket, which makes finding heatsink-fans a much easier (and cheaper) process. Of particular interest is that Nehalem-EP and Westmere-EP can include hexacore (and greater) processors. These cost a fair amount more than quad-cores, but make it possible to roll your own 12-core machine. Unfortunately, not all of these use the standard server sockets and configuring around them can increase compatibility issues. I do not recommend using anything higher than a quad core.

Some things to watch out for:

Places to Buy

eBay is the easiest and most convenient place to purchase used electronics on the Internet. It also allows for filtered searches, as well as the tools for determining the true market price of any old server motherboard, processor, or stick of RAM. On the downside, the prices can be slightly higher than you’d expect and if any part doesn’t work, it can be a pain to return to the seller. eBay alternatives exist Fed Up With eBay?

With millions of daily users, it only seems logical to use the... Read More , but I haven’t used many of them.

University IT center: Many colleges and universities sell off their used computer equipment after upgrading, often for a pittance of what they originally cost. Unfortunately, they offer first dibs to current students and faculty. But if you are a current or faculty member, a university is oftentimes a one-stop-shop for getting a complete server system on the cheap. Some universities even sell their used server hardware over the Internet. Try searching the Internet for key terms such as the name of your college and “surplus” or “auction”.

Public Auctions: Many state and local governments also auction off their surplus electronics. An auction is a good way to acquire an entire server on the cheap, since you don’t have to pay for shipping. But in my experience, public auctions tend to be messy and disorganized. I recommend buying from a univeristy over a public auction.

ServeTheHome provides a really great price-tracking thread on Xeon processors. While the price on second-hand LGA2011 (a much newer socket) has been plummeting recently, they are still not as dirt-cheap as LGA1366 and LGA771 processors.

Is Building a PC From Junk Worth It?

I’d say yes, but only provided you love tinkering with computers and want a good budget project to keep yourself occupied.

    I have an HP ML350 G6 server which I use for photo and video processing. LGA1366 socket, Dual CPU Xeon X5675 24 GB RAM. Tried to upgrade the graphics card to PNY RTX 4000 (160watt) and hit the tech wall at power supply limitation for the graphics card. There is not 8-pin output for graphics. I would also have to overlook the PCIe 16 slot downgrade to 8bit.
    Options I wonder about:
    1. Possible to upgrade the dual server power supply to something more compatible with newer graphics?
    2. Migrate the HP server motherboard to new chassis and power supply?
    3. Other options?
    Just wondering...

      Thanks for the comment!

      You'd have problems finding a server-class motherboard in the ITX form factor. Most server boards use a form factor called E-ATX (extended ATX). That form factor requires its own case. However, you shouldn't have any problems buying an ITX motherboard and just building your own home server with consumer class components.

    Just built one of these,
    SuperMicro Motherboard X8DTI-F $100
    Micron Server RAM 4GB PC3-10600R ECC 48gb (12x4gb) - $42
    Dual x5670 Hex-Core Hyper-threaded 24 "cores" total - $110

    So that's a 24 core/thread, 48gb rig running @ 3/3.3 Ghz beast, all for about what you'd pay for just the a skylake cpu i5-6600/6700.. I was hesitant to replace my creaky old fx-8320 setup since I don't game and and to get an intel system that was more than "is that all there is for my $500?" just did not make sense. But you cinebench cpu score going from 646 to 1370 that's $250 well spent..

    Thanks for putting the info together. It's quite an informative read, though not always accurate.

    * There are backplates for dual LGA771 boards, easy to find on eBay. These make mounting a Supermicro X7D series ATX board into pretty much any regular ATX case very simple. No McGyver style necessary. Pakrt # from Supermicro is SKT-0159, by the way. Same goes for the IO shields for the back of the case. Especially Supermicro and Tyan have fairly standardized IO connector layouts across several series of their boards, which makes it easy to find a suitable backplate, if it is not already included with the board. Supermicro IO shields are somewhat easier to find. Linus's video is inaccurate for the same reasons, by the way.
    * There were never any Hexacore CPUs for LGA771, this is simply a misinformation. Only Nehalem-EP and Westmere-EP do have Sixcores in their respective lineups.
    * The Supermicro board depicted above is an X8DTL-3F standard ATX board, not-E-ATX. I have one of these in a regular ATX case (Cooler Master Elite 431, to be precise), fits in perfectly.
    * You are only referring to ECC memory. Most server boards for LGA1366 require ECC Registered memory, which is different from "just" ECC. Same for DDR2 - if it's not FB-DIMM, it surely is ECC Registered. With the Nehalem-EP and Westmere-EP Xeons, ECC Registered DDR3 RAM might very well work in standard single socket, X58-based boards, because it's the memory controller of the Xeon 5500/5600 series being capable of addressing Registered memory, that makes the difference. Had a Xeon L5520 on an X58 chipset board with 6x 2 GB PC3-8500R memory, ran perfectly fine.

    I've been building dual Xeon based individual PCs for several years now, beginning with mPGA604, so I've had my share of experiences. Thought this article needed some errata, although nicely written up and addressing the key caveats to watch out for.

      • Duke2k
        July 26, 2016 at 8:05 am

        "Geared towards regular consumers" generally means, go to your local computer store and buy a complete PC or get "consumer-oriented" parts to build your own PC.

        This is slightly different, as it means to use mostly 2nd hand server parts to build a PC, for usually less money than buying a brand new PC off-the-shelf.

    Why go to all this trouble when you can buy a workstation? I picked up a Dell 7500 for AU$900.
    It has 2 X5660 hex core processors, 24 Gig of DDR3 ECC RAM, 1100W PSU, Nvidia Quadro 5000, 2 x PCIe 2.0 x 16 slots, plus all the x8,x4, PCI slots, DVD, etc.
    It's in perfect condition, and really quiet.
    I'm going to put another 24 Gig of RAM in it, plus an Nvidia gaming card.
    I've turned on Turbo and Hyperthreading ( 24 threads ). You can turn off ECC in BIOS and download the latest performance BIOS from Dell.
    No overclocking but 12 cores at 3200 are pretty good.
    PCIe 2.0 makes virtually no difference.

        I was just referring that you can't go above cca 600GFLOPs card with nVidia on x8...while 750 is 1.5TFLOP card...& newer (Tesla) systems are even faster!

    Also: the money you save buying server-parts, the money you'll spend on bills.

    Servers' cpus are low frequency and not easily overclockable. You need "brute force" for gaming, that means high frequencies. It's easy to have a bottleneck between CPU and GPU.

      DX12 is showing surprising gains in multi-core systems. An 8-core PC might (I haven't seen it tested yet) outperform today's four and two core systems.

      I should have mentioned the power consumption. In countries like Germany where they pay 40 cents per kilowatt, a system that runs at around 400 watts with a normal load is going to cost a fortune over a year.

    Lots Of Cases Have Removable Motherboard Trays.

    Keep The Tray And Put The Case Away.

    Some Trays Have As Much As 11 Expansion Slots, And Are Compatible With Lots Of Form Factors.

    For Any DIY Kind Of Guy, I Would Say This Is The Beginning Of A Beautiful Friendship.

    I recommend buying a workstation model off eBay and pay the shipping. I recently pieced together a dual quad core Xeon workstation with 32 gigs of ram for about 150 delivered. Throw in a old HDD and a recycled HD 6950 and I'm ready for Steam on Linux.

    I repurposed a workstation and beefed it up with mega (cheap) RAM, dual Xeon Quads, and surplus graphics card (dual sli) for $500. Works beautiful. Been using now for 2 years. Runs strong.

      Nice! Have you run any DX12 games? I'm waiting for a Polaris GPU at the moment, so can't test any games out.

        I'm actually not a gamer. I'm running business applications on the beast. The video cards are Quadros so I'm not sure about DX12.

    I'm an IT guy. I've been using server parts at home for ages.
    Here's a few more notes:

    1. Server Motherboards usually have a hardware compatibility list for RAM. Depending on the manufacturer, some boards will be better or less well behaved with RAM that isn't qualified for the board. You're best off getting a working motherboard that's already populated with RAM or else buying a board first and finding known-compatible memory. Some motherboards (Tyan, Supermicro) are pretty obnoxious RAM compatibility.
    If I can't find compatible RAM, I usually try Crucial modules. Crucial is willing to guarantee compatibility of their modules if you buy from them, so I'll usually go look up what modules they recommend for a board so I can purchase those.

    2. Servers handle cooling differently from desktops. The normal means of cooling a server system involves a large passive heat sink and a row of extremely high-RPM fans blowing air over those heat sinks. Workstation-class Xeon motherboards behave more like desktop systems and may offer spacing for large tower coolers that may or may not be an option on Server boards, but in any case, finding a Xeon motherboard that handles fans like a desktop is a hassle and may not be possible. If you're using the cooling systems that the server boards ship with, you're probably going to have a computer that's going to be obscenely loud and tower coolers with socket compatibility for LGA771, 1366 or "Narrow" LGA2011 commonly found on Xeon systems will be exotic and probably more expensive than one would expect.

    I tend to like Asrock and Asus Workstation motherboards better than actual server boards for my home rigs because I don't like having a machine I can hear while I'm in the shower, which is the likely outcome of buying a complete Supermicro, Tyan or Intel Server.

    3. Power consumption. Big-boy Xeon CPUs are power hogs. That may or may not be an issue. The 32-thread dual LGA2011 PC in my back bedroom costs me about $36/month to leave on all the time. That's not insubstantial.

    While I'm at it, Kwannon doesn't mention LGA2011. They're very affordable as well and can be found in 8, 12 and 16-thread variants. No one needs that for gaming and games won't take advantage of that many CPU cores, but if you want or need a test lab or do serious content creation, they're marvelous.

    4. With regard to PCI-express, most server motherboards will have a mix of 4 and 8-lane slots. They might also have PCI-X (which is explicitly not the same thing as PCI-e) slots or expect to use a riser card (so cards are parallel rather than perpendicular to the motherboard) for expansion. As it happens, many PCI-e is actually designed so that physically larger cards can fit into smaller slots as long as the back edge of the slot is open. On server boards this is often the case. You are not crippling a 16 lane PCIe graphics card by sticking it in an 8x slot. Even on gaming motherboards with multiple physical 16x slots, most of those slots are electronically 8x. The subjective difference for anything but benchmarking wankery between having a card in an 8 or 16x slot is pretty much zero.

    5. If you're running desktop Windows on your server motherboard, some stuff is going to be weird. You may find, for example, that power management doesn't work right because of differing firmware assumptions associated with the motherboard. Xeon CPUs don't have integrated graphics, so if graphics are onboard, they'll probably be pretty crummy (Aspeed? Matrox G200?). If the server is new enough to have a built in displayport connector, it probably won't support audio out from it, no matter what driver you load. You also won't have as many USB ports as you'd typically have on a desktop and you'll probably have a weird ethernet connector that's set aside for management over IP networking (IPMI) rather than normal duties.

      Excellent tips. As always, it's very much appreciated. Also thank you for adding the w to my name. :-) Apparently you know something of Eastern religions.

      I did mention LGA2011, but it's still a fair amount more expensive than LGA771 and LGA1366 builds. The latest prices show a good CPU selling for around But the price is starting to fall so rapidly that LGA2011 is probably an even better buy than LGA1366 parts. ServeTheHome shows them going for around $70, which is a ridiculously good deal.

      Also thank you for mentioning the difference between workstation and server boards. That's a really important tip and hopefully our readership checks the comments out.

      Are you based in Europe? Your power costs suggest either high 24/7 loads or a really high per-kilowatt costs.

        That machine draws a touch under 660W from the wall under continuous load. It's a big computer. It duplicates a machine that's sitting at a datacenter for my hosting customers and it also hosts my storage setup and any testing systems I need. Yes, my energy rates are fairly high, but that one computer replaced four systems, so I really don't mind the cost.
