About this 3D model

Summary: Once I found how fragile the heat sinks were and so easily dislodged by cable movement, I designed this case to keep the cables away from them. The mega just fits into the slide in the bottom and the whole thing fits on the 2x4 behind the plywood. My fan power supply wall wart came with two connectors, so two fans. I used Noctua A4X20 (40X20 mm) fans.
