I'm getting close to finishing my cabinet, down to the little details. I need to come up with some kind of retainer that will hold the monitor plexi in place. I don't know what was originally on this cabinet, probably something that was attached to the control panel.
Check out the picture below. The wood piece on the bottom has two levels routed into it. The first is where the bezel sits in, then the plexi sits in the lower one. I'm thinking I could just build something out of wood, then use furniture bolts from the back side to hold it in place. If there is something simpler, please let me know.
