I didn't build the machine, and there are no markings to identify the manufacturer (as far as I can see).
To get the sides off, I have to take the top off first (slides back), then the sides lift upwards. The large block of green foam is not standard, and neither is the extra hole in the rear. I think the black pads, and white foam blocks might be. It has 5x 5.25" drivebays, and one 3.5" visible bay. It uses metal trays to carry narrower drives in the 5.25" cage.

Does anyone recognise this (admittedly old) case?
