While building my MAK I taked a peek at MAK boards. Here is an example for the MAK MK V. DSUB connectors points to the top and lays in the edges. Switches are deeper than the capacitors. PSU Adapter is fixed for ATX PSU. All this facts make it not easy to build it in a dedicated case. But the technique is fine. Composite and S-Video output via AD725 chip is integrated.
