Mini ITX vis Mac OS X

First, I won't deny my general ignorance where many computer-related matters are concerned.  I generally only get as involved in the tech side of things as is necessary to accomplish what I'm out to do.

OK, so here's the question.  Let's say one were to put together a nice new Mini-ITX based system.  Would it be possible to run the new Intel version of Mac OS X on such a machine? 

The obvious question here is why, given the availability of the mac mini.  Well, the Mac Mini doesn't quite hit the mark, whereas an optimized Mini-ITX based system running OS X would hit the mark perfectly, IF IT COULD ACTUALLY WORK.

So yeah, just looking for a general yes/no on this - please save your flames for another day.

Running cracked OS X can be a real pain in the ass. If you're looking for a flawless OS X experience, get a Mac Mini, and if you like OS X enough, sell the Mini on eBay for like $100 less than you paid and get an iMac.

You indicated that you're not too computer savvy, so I'd definitely recommend getting the real thing. It'll save you some headaches.
