I think if I go to that trouble I'll build another better one. This serves a purpose for the moment, and gives me some good ideas for the next one, RE accurate sizing and layout, and basic router jig setups req'd.
This rack took me about 2 hours to knock up out of free material. When it suits me to build a nicer one or few, I've got good dimensions to take off, a list of improvements, and a jig system to route cutouts as req'd to whatever dimensions I deem most suitable.
I hadn't thought about strip lighting, but that could be housed in a routed trench in the top panel and would be quite nice, but then I'll have to pretty up the rest of the room to do it justice, Hmmmm...
