Yeah I'm going to put doors on everything. I'm working on those currently. Just picked up a bunch of 3/4" MDF from home depot and a router.
I have thought of doing something for those ones. Like a face over the one with a sub that's maybe just a frame with cloth stretched over it so the sound can travel. Then something to cover up the stereo too. I don't have any great ideas for that yet so I'm just going to save all of that for last
also I have my work top started as well. Just need to attach it and router the edges. It's two layers of 1/2" MDF.
