You might be able to do it for less, but you'd still be spending thousands of dollars to do it. Plus you don't get support.
I think the sweet spot for hackintoshers is the exact market Apple is avoiding. Basically a cheap version of the Mac Pro but more powerful than an iMac. For just under a grand you can build a sweet quad core machine that blows an iMac out of the water and probably comes close to a base Mac Pro in terms of power. If I had to spend more than a grand, I would probably just buy the real thing.
