I have made an enclosure for the PC Engine AV amplifier that you can get from eBay etc.

Please check your particular board in case it is a clone.

Future Ideas:

As the mechanical parts are complete, the case can be further stylised to match the shapes and contours of the PC Engine console.

To secure the PCB additional features can be added, such as wedges and shelves near the back of the case. Standoffs on the bottom etc.

The lid can be altered to use a clip feature to keep it secure rather than glue etc.
