I'd second this. In general, Apple hardware is not terribly expensive for what you get (assuming that you don't value things like software, industrial design, power efficiency, noise, compactness at zero because you personally are not interested in them).

A Hackintosh lets you get combinations of hardware that Apple doesn't sell. It also lets you add or remove features that Apple doesn't offer on any model such as replaceable components and large/loud/inefficient machines. In many cases this does end up being cheaper because you are purposely choosing to use fewer or lower quality components.
