I finally had some time to work on it today. I got the monitor mounted after 3 trips to different hardware stores in search of the right sized bolts. I also drilled the speaker holes. I have computer speakers which will sit behind the holes. I also tried to dowel the top half to the bottom half but messed up one of holes so I need to fix it.
Tomorrow: Finish doweling, install door under monitor, slot cut, first coat of stain.
