This year, 1293 had a board on Ockham for electronics. Imagine a big piece of aluminum bent 90 degrees. The RC and breaker panel were mounted vertically, with the Victors (no Spikes) on the bottom. Throw in some nifty water jetting to save weight, and you've got a right purdy electronics board.
The one problem I've experienced with it is that it's sometimes hard to get into there to work on the Victors, as we put it nice and deep inside the robot. (If you look at
this picture, it's between the tower with the van door motor and our arm covers. The triangular hole is from a piece that both anchors our arm and shields the electronics.) If I could do it all again, I'd try to remove some more weight, and perhaps come up with some other mounting scheme, probably a bit more exposed with protection.
However, it does allow you to get everything out easily enough, once you disconnect the wires. We've never had to do it, though--clean living, I suppose. I'll try to get a picture of it this weekend.
