Can I put Mac OS X Snow Leopard on My Custom Build

Solution
You may be able to, it's more complicated than installing Windows on a PC (or OSX on a Mac) since OSX is specifically made for Macs. One difference between Macs and PCs is the BIOS. While the hardware is generally similar Apple uses a custom EFI BIOS, which isn't exactly a standard PC BIOS. Also, if you have an AMD CPU it's harder to get that to work since Apple has never used AMD CPUs, OSX is optimized for Intel with no AMD driver support.

There are guides online to creating a "hackintosh".
