We've used plastic pegboard recently to good effect; we don't have to drill nearly as many holes. We usually mount the battery box and compressor directly to the frame, and put the cRIO over some additional support; not sure if the roboRIO will require this.

I absolutely agree that the control board should be non-conducting. It doesn't really matter when everything is done correctly and nothing comes loose, but it reduces the chance of a jolt or a short when things don't go quite right. For example, we are salvaging last year's drive as a base for prototyping this year. This involved pulling off the manipulators, and several of the now-spare controllers. The kids left the supply wires for a couple of the talons in place, with breakers still in the PDB. Since they were sitting on a non-conductive board, there were no ill effects. If they had been on an aluminum board, I could only hope that the breakers would have tripped immediately!
