The control panel is constructed of 1/2" medium density fiber board. This seems to be the material of choice when it comes to cabinets. Construction is fairly simple. I used a circular saw with a plywood blade to make the cuts. The holes were drilled with 1-1/8" drill bit. The are much better than using a hole saw as it chips the wood away, resulting in much less dust. The holes for the trackball and flight stick were made with a scroll saw. I drill the holes for the blind insert nuts using my dremel and its optional depth gage. I used epoxy to glue the sides to the top. I then used inner angle reinforcements on the corners.
The cabinet itself will be mostly 3/4" mdf.
The basic design and dimensions of the cabinet and control panel:

This is my completed control panel, and my temporary setup for testing/playing:
