Well okay, datasheet, not article. Got my supplies from Maxim (the chip maker, not the magazine) for converting an Xbox devkit power supply to power an actual computer. It was a nice deal - Three tiny chips to convert the supplied voltage into the -12, -5 and 5 I needed. One problem; the chips can supply up to the amperage the motherboard I have needs, however when the put out that much power they tend to be off of their rated voltage by as much as 3/4 of a volt. Now motherboards have gotten more tollerant as time goes by, but when they need 5 volts, 4.3 just won't do.
So it's back to ebay. Found a tiny little normal power supply (a 90w one meant for old gateway computers) from Newton Power ltd. which should fit the bill. And only 10-15 bucks depending on who I buy from. So it lacks a little in the conversion aspect (now I'm basically just using the case and built in USB hub) but whatever gets it working.
