I've heard that some projectors are somewhat noisy and was thinking instead of putting in a mount, what do you think of building a shelf that hangs from the ceiling, more like a box. this would contain the noise or at least keep it coming only from the front. Of course, a box may look a little out of place, but it would sort of hide the projector giving more of a clean look. At work, we have a drop down motorized shelf which is nice, but that is a little beyond what I need. I'm thinking it would be just as easy to fix for removal if I sold my house, as long as I planned it ahead of time. What do you think?
