1. This desk needs to be built-in as opposed to some store bought unit that sits away from the wall because of baseboards. You know ... the desks that lure all of your objects to the back so they can fall between the space and onto the floor to be lost for several months.
2. I wanted the component box to hang or "float." Partly because my house is old so nothing is level, but also because I liked the idea.
3. I wanted cable management because I have some OCD issue.
4. Lastly, but most importantly, I wanted it to look like metal ... \m/
Step 1: The Basic Carcass
The top is two layers of MDF cut to 24" x 6', which I laminated together with glue and screws. You can see how OCD driven I am because I laid out a grid just for the screw positions.
The cleat is a 2"x4", which I half lapped in the corner for an interlocking fit. I tapered the bottom corners, painted it to match the wall, and secured it to the wall studs.
The component box uses rabbets for joinery with glue and screws. The dado in the middle is for a shelf. The holes are for cables and venting.
