A few notes from the FAQ:
Just because you might get Windows running on a Mac, or Tiger running on their Dell, doesn't mean it's legal.
...
The challenge comes in the technical means by which the operating systems load. Windows loads itself using something known as the Basic Input/Output System, or BIOS. Apple's Intel Macs, however, use a newer technology known as Extensible Firmware Interface.
...
Q: What about running the Mac OS on a non-Apple PC?
A: There isn't a legal way to do that, given that Apple doesn't sell standalone versions of its operating system. Because all Macs come with some form of the Mac OS, the retail boxes that Apple sells are only licenses to upgrade from one version to another.
