The aircraft manufacturers do similar things, though they seem to be goofy, in the enviroment that they operate, it's actually a pretty smart setup. What's funny is most people, even mechanics never get to look at the back of an avionics rack, unless they are trained in avionics. The front is all nice an pretty with boxes, and the back is covered with terminal strips, where there are thousands of 18 AWG wires making connections back there.
