I have been looking for a small atx power supply for some time now and i think i may have found a solution.
Emachines have that computer that looks like an i-mac and when i looked inside of it i noticed that the powersuplly was much smaller than that of a regular atx psu. The dimensions were smaller at all ends, surely b/c the computer itself is much smaller than normal ones.
The only problem now is locating one for a reasonable price. I have just searched the net and didnt come up with anything but i just thought i would throw this possible solution out there for anyone who is trying to create a small profile box for their player. If anyone finds any info on the emachine units or ones similar to them, please post them on this board.
