I think something like a shuttle computer would be comsidered min-itx. I know this guy used to sell a 200 watt power supply on e-bay that works with the via epia m/b's but said they could be retro fitted to power amd m/b's. I have a 2100 xp+ and it runs hot in my vx without the ac on. I runs everything smooth and quick, but if I keep it clocked to the fullest potential, it starts to cook the interia of the truck, they run around 130 degrees. If you haven't bought the cpu yet, look for the barton core fr amd sicne they run a lot less power like 35 watts and therefore are cooler running. I'm considering an upgrade to that cpu since I live in fl and it's hot to begin with already. let me know if you need any help.. by the way, it vehicrosspc in mp3car. Oh, if you wondering, I run a 400 watt inverter to power the computer along with the usb devices... but that too creates some heat so I think I'm going to redesign everything to run cooler.

I thought computers run on 12, 5, 3.3 and 1.5 volts.

Couldn't a simpler power supply be used rather than using an inverter to 120v, then power supply back down?
