Firstly, "caps lock is not cruise control for cool"
Second, I'm skeptical about how effective that design will be once you actually have all your PWMs, relays, and sensors wired. In order to maintain the slide-out ability, it seems to me you'll need a whole mess of long wires connecting everything, resulting in a very messy setup which will be quite a bother to debug. And won't you still have to unscrew every motor wire and unplug every sensor and relay to remove that box?
