Step 4: Case
The case is a simple 200 x 200 x 210mm cube-shaped box made of 5mm MDF, with the side parts being mitered with a 45° angle.
On the front I made cutouts for the speaker, the volume knob and the power LED. It was covered with light-grey speaker cloth and clipped on with wooden dowels.
The back shows holes for the power chord, power switch, audio jack and input switch and is held in place by wood screws.
