Interesting question,is it possible to.....

It's possible, I've seen it done a few times. Don't expect the Mac OS to be running at full speed on a PC. Emulation will slow it down a lot.

EDIT:
Man, I forgot. There's an x86 release of a certain OSX that will run on certain PC processors. I don't know much about that at the moment though...

Okay, so here's the details I found...

You need an INTEL machine for OSX x86 to work, with SSE2 for just the OS to work, and SSE3 for certain programs to work.

You can't install it on a partition. It has to be the only thing on the hard drive.

You also need the ISO of OSX on a thumb drive, and use a Debian Linux LiveCD to install it (won't get into details here, simply because I wouldn't know what I was talking about )

Note, that's the HARD way of installing MacOS on a PC, at full speed natively. There's also the way of installing it inside Windows via VMWare, which to me is garbage and useless anyway.

There's a leaked software that permits that but only on newer Intel procesor. Remember, intel is going to make future apples processors you can google it for more information.

And here's an article about running it with an emulator http://www.windowsdevcenter.com/pub/a/windows/2005/01/18/PearPC.html
