I have a Dynamo shell... I believe it's an HS-5 but am not entirely sure. Unfortunately I cannot see what is posted at the dr zero site so it maybe the same manual that I have (the security filters my work PC are blocking it). The title of the manual is "Universal Video Hardware System" and it has diagrams, wiring schematics, etc. but no measurements. I can manually measure as well but thumbing through the manual it seems these were standard cabinets with standard control panels designed to be adopted for custom use (for example, there are instructions on horizontal vs vertical monitor mounting, cutting the marquee to size, drilling the CP, etc.)
Mine had a 25" monitor. The control panel has hook hinges at the top, and a long hinge along on the bottom that allows you to swivel it down once you unhook the top to get into the area behind the CP. The CP itself is mounted to a large square piece of removable 1/2" thick plywood that is mounted inside the cabinet at an angle.
