Since OS X Lion was released, if you wanted to build a Hackintosh (and I would like to think the tutorial on this site is the most comprehensive how-to out there), you had to get your hands on a copy of Snow Leopard, install that, and then upgrade to Lion. There were often complications along the way, to the point where I refrained from upgrading to Lion. Thanks to tonymacx86, however, hackintoshers can now grab Lion from the Mac App Store and install it natively from a USB drive. Here's the blurb:
