Grats on your first motherboard swap! That sucks that it doesn't fit though. I'm sure this is obvious, but make sure you don't have the motherboard sitting on the case like that when you turn it on. I saw that happen once. There was a lot of sparking, and the guy working on it had his face over it and didn't realize that he had sent power to it. Zapped him in the face and fried the board. I was at the other side of the room and heard a loud pop and then pained expletives.
