OK guys, I'm no woodworker but I finished my built in wall unit for my gameroom and here's a pic. It is 84" wide, will easily hold a 36" TV. I bought the 3 base unfinished oak cabinets and then built the rest from birch plywood and assorted hardwood pieces. Probably the most fun was boiling the 3/4" laser cut trim to fit those curves. It has about 5 coats of enamel on it, wet sanded with a finish like formica. I also crown moulded it into the existing crown.
The hint of black you see in the center of the TV hole is a bull-nose routed hole for plug and cable TV access so no cords will show when filled with electronics. Most every panel has a routed hole in back to pass cords around.
