I built this to house a Canakit 3 channel light organ board and its plugs and fittings in a safe way I added a piece of plexi glass to the front to make the interior leds visible. access to the potentiometers and input plug and selector switch is in the side and mildly shielded.
Also included is the bare board mount for you to make your own box and save some time if you want.
