Is it possible to mount a BG808 vertically. I would like to build a box for the projector so that lenses point toward the ceiling and have a door on the top with a silvered mirror that can be raised to 45 degrees to project the image onto the screen. I also intend to build shelving down the front to hold some of my DVDs. The height of the mirror would be ideal for the proposed position of my screen, and the floor space taken up by the projector would be a minimum. I would have to think about wall clearance for ventilation. I intend to leave the bottom open so that when the mirror is raised would act like a chimney to aid cooling. Comments appreciated.
