Ok, for my next project, I'm going to be making the smallest computer I can. Now, because of the space constraints, I'm probably going to end up using like a 73W power supply, and heat will be a major issue. I'm basically thinking of either a Celermine or a K6-3+(figure being a mobile CPU, it's pretty low power), so how do their power consumptions compare? Or maybe I'll just use an OG Athlon 
And while I'm at it, do notebook CD drives just use regular notebook IDE connections?
