Or better yet a way to load Mac OS on a regular PC?
Yah, use a nice KDE Linux distro like Kubuntu, SuSe, or Red Hat :P
Lets you customize the desktop, too!
Actually, I do recall people hacking Mac OS to work on a PC.
Of course, it probably didn't work very well since that OS is tethered around Apple's hardware (I don't mean that in a bad way -- just pointing out differences)... and I don't think Apple liked it much that their OS was being used where their hardware wasn't.
