Build your own 50W PC

George Ou at ZDnet shows how to build your own PC out of commodity parts using only 50 watts. A crucial point for him is the efficiency of the power supply. He does use regular disks. I would have expected one flash memory "disk" and one spinning disk, but maybe the power management software isn't yet able to distinguish and power down the more energy hungry disk first.
