Hi Kimbal.
Yep been there tried that.
It's not as easy as they make out. I tried putting OS10 on my PC but the hardware wasn't up to date enough to run the Mac OS.
So I ran Ubuntu instead.
My PC is getting a bit long in the tooth but the good old LGA775 Quad core still runs happily with 4Gb of DDR2 and my slowly fading 9600 1Gb graphics card.
