That brings up a question! Sushi, do you or anyone else know what the minimum depth of a rear projection cabinet is? I seen a setup at a hifi store that had the projector mounted on a rack that projected the image onto a mirror and then to a rear projection screen material. seems to me though the depth was about 4'. I really liked this because you could also store you audio and video equipment behind the wall out of the way. This room could also be cooled and ventilated well. Just something to consider if you have the space to loose, or use, (however you want to look at it.)
