How do I clean install Mac OS X Snow Leopard on a Windows PC?
Make a backup with Time Machine (or Carbon Copy Cloner or SuperDuper!), Boot from the install disc by holding alt key (?) and select the install disc with arrow keys and hit enter. It may take up to several minutes to load everything, so please, be patient. Select your language and click the arrow (->). It will now prepare the installation and this may again take up to several minutes so be patient. You should now be at the "Install Mac OS X" screen. Select Utilities from the Menu Bar (the grey bar on the top) and open Disk Utility. Select your hard drive or partition from the left-hand-side menu (note: if you have installed Windows on to your Mac and wish to keep it as it is, choose your Mac OS X partition because if you erase the whole hard drive, your Windows partition will be erased as well) . Click "Continue" and an agreement will appear, click "Agree". It will now ask you where do you want to install it. Select the erased hard drive/partition you just created and click "Install". The installation process will take about 30-60 minutes depending on your computer, When the installation has succeeded, it will ask you to restart the computer. Simply click "Restart", Enjoy the Welcome Video, Select your country or region, Select your keyboard layout, Migration Assistant will now open so if you want to migrate your data from the backup you made earlier, select "From a Time Machine backup" (or "From another volume on this Mac" if you did not use Time Machine), there you go It will then reboot and voilà, you are done!.

I would warn you that installing OS X on a Windows PC will be less than ideal in terms of performance, issues encountered and overall experience. The point of OS X is to marry the hardware and software seamlessly, and Apple goes out of its way to make things difficult for non-Mac machines.
There's always the x64 (i.e. Windows-compatible) Mac Minis and iMacs in case you simply can't get it working, and if you buy now you'll get a free copy of OS X Mavericks when its released, which provides huge leaps and bounds over Snow Leopard.
