You will get many

icons because all of this is answered in the FAQ's.

Compaq's are known for being proprietary. I would actually open the PC and see if they use a standard 20/24 pin ATX connector and not some 16pin or 18pin or 12pin black thing. If it has an ATX, then you can power it from a DC-DC. Which is a whole different ballgame.

We cant judge a systems power draw based on form factor. You can get an embedded solution in itx form as well as a P4. If you just say "how much to power an itx mobo", the answers range from 11W to 160W. We need more info. And you do need to search for which power supply will work as they put out different amperages on different rails. A 320W PSU may not be able to power it but a 220W may be able to. It has to do with the rails (most notably the 12v and 5v) and what you plan to draw off of each. All this is answered in the FAQs.

As for cables, eBay, the mp3car store, walmart, target, compusa, anywhere.
