SmallBoat, I like the Confidence arrows. But all kidding aside, your sketch is great. I wouldn't dare post one of mine that I drew by hand.
I definitely will have some kind of latch. I liked the suggestion of magnets, but even though they wouldn't be super strong, the idea of mixing magnets with data signals is not computer 101.
Doug, at least I have a wireless keyboard and mouse. So they are making progress.
Since I found sketch up and watched a tutorial, I have been playing a ton on there. I think I have come up with yet another design.
This one will span the entire desk. I will have holes in the vertical supports to pass the cables and a hole on the end by the outlet too.
By extending the lip over the desk, I think that will help hold/support the verticals, especially on the non-recessed end since I don't want to have any visible screw holes if I ever take the box off.
I am thinking I will either need to attach the vertical supports to the nailer by screwing down into the support or maybe use a pocket hole to screw up into the nailer. I still need to figure that out since the opening is only 1.5" deep.
I also will not have a wall right against the desk, unless I need it for stability, but I think I'll be good without it.
