I have an old school Dell GXa sitting around. All the hardware is obviously obsolete but the case is in good shape. I would consider purchasing a newer motherboard (P4 or better) for it and giving it to one of my friends if I knew what kind of board it took. I have been looking on Wikipedia in an attempt to see what form factor the motherboard is but I cannot find it. The bottom half of the board accepts another smaller board (I believe it is called a "daughterboard") which slides in at a 90 degree angle. Here is a picture of what it looks like:

Considering the cost of a new case (as little as $25), I wouldn't waste time trying to reuse this one - as one answer below states, the mainboard is custom and not one of the standard sizes used in most generic systems so you're unlikely to find a board worth you time upgrading to. – Multiverse IT Nov 7 '10 at 12:38
I know $25 isn't much, but I just don't want to be wasteful :) – ubiquibacon Nov 7 '10 at 17:33

The large-name computer retailers tend to use custom engineering for things like this for various reasons. You are unlikely to find a replacement motherboard for that machine from anyone but Dell.

Yeah, I knew it was a possibility that this was a custom board, but I was not 100% sure since I have seen some other old computers that had a similar configuration. – ubiquibacon Nov 7 '10 at 17:33
