Power Supply

A stock nameless white label power supply comes with the case, but that's not good enough. It's fine for initial building, but if we're going to load this machine with a new 6 Core CPU and 2 extra video cards, and 4 GB of RAM then we need to up the quality of the power supply. We'll just throw the old PSU up on Ebay for $10.
