I have made some pictures with the SketchUp drawing:
The sides do not provide structural support and are attached to the frame with removable screws
here is the frame without the side panels and control panel
The frame has two separate pieces that can be split and transported individually
here is the upper frame with both LCD screens. I Think I overdid the frame, but as the LCD marquee is heavy I did not want to take any chances.
And I'm no structural engineer
The bottom part has even more structural support than needed I think.... The computer is housed in the upper deck of the bottom frame. The subwoofer in the bottom part.
If anyone wants to use the sketchUp file for their own project / measurements, ect.. you can get it
