Is it possible to run Mac OSX server on a x86 PC ... ? Any thoughts ? (our general manager wants to aquire half a dozen mini macs for some servers and he wants some testing with the mac osx server but i haven't got the mac machine to test drive the mac osx server for a couple months... any thoughts if on how i can do this on a PC ?
Mac OS X is only supported on Apple hardware. It is possible to install it on non Apple hardware have a look here. It may be easier (and safer) to just wait for the server to arrive.
It's not supported, but that isn't to say there aren't plenty of guides detailing how it can be done. Here's the one I've used previously (edit: not in a work environment) which details the process quite thoroughly.
Biggest problem thou is always the hardware support; Apple put a lot of work into making OS X work with their hardware, but the guide details some parts that are known to work fine.
As radius said, it's a violation of Apple's terms. It's also quite a hack and wouldn't be an accurate way to evaluate the feasibility of the proper setup.
