If I had the space and the dosh to spare, this is what I'd like to make. Not a Hackintosh, but a Frankenmac, a proper one but with just better components.
Seems much easier to do than a whole Hackintosh with a lot less guesswork, but I still wonder if/when Mac's new desktop comes out and what those specs will be. We're SO overdue, and they're ignoring that demo at their peril.
