Ah. Just saw that.
Did you position the brass mounting posts properly? If you think you did? not good enough. Get the board out. If things were fine before then it's likely by transferring it into another case you have a short somewhere.
Do you still have your original PSU? try that. Have you trapped a wire somewhere? look for that.
ETC. Retrace your steps, process of elimination.
