Sorry, so is this a built rack or asking for advice on it? Either way I think it's a pretty awesome lunchbox to play with the brute.

In my subjective experience, limitations force you to be creative. YMMV

I also find that a mouse and keyboard are like a filter that allow my analytical decisions through and almost completely block that "right brained" intuitive, stochastic non-deliberateness. When working with hands on knobs in real time it seems to me that I can get to a place where half of me is on autopilot, and the other half is anticipating complex patterns several steps ahead. That is just me though.
