There are no specific requirements for what you mount your electronics to. However, please reference R27. Note that most, but not all, of the electronics do not ground to the case, and thus could be mounted to anything (if set up properly). Check to make sure on yours, though.

Oh, and one other thing: Use Lexan (polycarbonate) instead of Plexiglas (acrylic) if you do go that route. It's going to be a pain to replace all that cracked plexi... Or just use wood for the bellypan from the start.
