Through normal means, you can't install Mac OS X – the operating system for Macs – on any PC. OS X needs to be installed on Apple hardware or, in the case of OS X Server or OS X Lion (the latest version), within a virtual machine, running on Apple hardware.
Anything else is against the EULA and not possible without hacking.
Subject to the terms and conditions of this License,
unless you obtained the Apple Software from the Mac App Store or under a volume license, maintenance or
other written agreement from Apple, you are granted a limited, non-exclusive license to install, use and run
one (1) copy of the Apple Software on a single Apple-branded computer at any one time. For example, these
standard single-copy license terms apply to you if you obtained the Apple Software preinstalled on Applebranded hardware.
