I just worked on this some yesturday, and these are the results I have in the picture. I've been wanting to do this for a long while, to have motherboards stacked in a rack configuration using nothing other than the motherboards themselves and threaded steel rods. I had to make the holes on the motherboards larger using a diamond bit on my dremel, and very teadiously carve away at the magic compound (PCB) that contains a secret mixture of equal amounts pixie dust, and wood glue. when I was done, this is what I resulted with as you'll see in the end picture, the only thing that makes me nervous is the fact that it has started to put pressure on some of the rods causing my asus board on the bottom to bend slightly, this is because they are either bent, or for some reason perhaps the brass nuts I'm using weren't threaded completely straight up and down, either way I'm not TOO worried about it. No I have no actually powered them up yet to see if they work, thats another thing I'm working on, more outlets. I will post when I do. I do have one question of anyone who stumbles across this! Does anyone have an idea for some kind of consolidated power supply situation with these motherboards? I plan on using some longer rods if this ends up working out fine, then I could stack, say maybe 10 of them at once (thats my goal). Would that mean I also have to have a stack of 10 desktop power supplies? Cawm on, I'm trying not to kill my hydro bill.
