I am going to locate my equipment in the wall with rear access to the back via the garage. Any suggestions on design. Obviously I want to protect the gear but I am concerned about insulating the box and keeping my equipment from overheating. So far I was considering building a 5'x 2'x2' (HWD) box. I was going to used MDF to construct the interior allowing for an adjustable shelving of some sort. I would run an outlet to the rear inside corner. As for the door I was thinking of tinted glass. Tinted enough that my remotes would work but no bothered by the lights.
