A local customer approached me a while ago about building a kit for him, and we went back and forth for a while before coming to the conclusion that what he really wanted was a fully upgraded Stereomour with a remote control. In order to do this, I had custom top, front, back, and bottom panels made, and I shrunk the top panel to a 10x10 in the process since the controls and jacks all moved off the top panel.
I cut the wood base down and used my scroll saw to remove enough material to get everything tucked in there. It was a very tight fit! Standoffs in the corners and along the side edges hold the top and bottom panels together.
