nope, not unless it has the very very narrow range of hardware the OS X_86 supports AND you figure a way around their copy protection they use
biggger and more imprtant question is why anyone would want to do so other than just the novelty of it?
From what Ive read Apple has stayed with the mach3 microkernel, just setup for Intel, stupid move, costs performance. OS X in general, like windows, doesnt perform well under heavy loads. Both Apple and Microsoft have chosen to use speedy hardware to hide a multitude of sins all in the name of eye candy so they can have more sales. If thats cool to you, by all means knock yourself out.
