After seeing what some others have done, and needing more 5v and 12v power supplies, I picked up 3 miniATX and 2 regular ATX power supplies on clearance to convert for DIYC purposes. Below is the first of the miniATX's that I finished this afternoon. It has terminals for 3.3v, 5v, 12v and ground. I also converted the built-in 110/220v switch to act as the on/off switch with 110v as the "on". It was pretty easy and I recommend this as a cheap and easy power source for anyone in need.
