Power Supply Board
There is a fair bit of wiggle room on and above the board, so you can fudge a little on the cap dimensions. In particular, the cap they used for EC12 was a very short "low profile" one which is hard to find, and was easily replaced with another (more "normal" sized) capacitor of the same values.
