Hi XXXXXXXX,
Running Mac OS natively on PC hardware is not possible, However you can run Mac on a PC if you use an emulator.
Just as Mac can run XP in Bootcamp or Virtual PC then a pc can run mac in an emulated space like PearPc.
There have been some interesting roumors for almost 2 years now regarding a new kind of emulator that would allow Mac os to run on PC hardware,Again it is an emulator however it is a micro emulator that will allow for near native performance.
Hope this helps
