Something shorting under the board maybe? A misplaced standoff?
Try running just the board, CPU (with fan) and psu outside of the case, all other cables disconnected.... Then if that works add memory and other bits one at a time.
I solved it. The source of the problem is so embarrassing I'm really not going to post it here...
Do you mind explaining what the problem was? I am having the same exact issue.
Yeah man what was the problem.

Check to make sure the button is not stuck on the chassis panel. For me, the button was being slightly depressed by the panel, and I had to use a screwdriver to adjust the panel enough to make it so the button was not touching the chassis.
