Here's the victim, you can see evidence of the arc by the mounting hole, and the 1 capacitor that's obviously toasted, the other being on the bottom left (you can barely see the top is deformed). I hooked the board back up, but it didn't show any signs of life. As I mentioned before, I assume there's more than just the 2 capacitors damaged.
On a brighter note, here's the new board.
