I bought a new house with a media room. It is not fancy but at least it is dedicated. The problem that I have is that there isnt a closet for the equipment. I am kicking myself now for not having it put in during construction so I left to add it now. My question is, how big should the closet be? HxWxD and should it have a rack built in or a free standing just pushed into the space? I am planning on having a vent fan tied into the air return of the AC so i think i am good with the cooling but I just dont know how to go about the rack and the size of the closet. any help would be appreciated.
