I want to buy a professional ceiling mount for my Dell 2200MP that sets the unit upside down, but I'm concerned about the effects this may have on the projector.  I recall a post that indicated the 2200MP made more noise in the upside down position, is this true?  I'd also like to do the upside down mount because of the nature of the projector's image "throw", (placing the center of the image above the projector, more suitable for a business presentation from a tabletop).  Mounting the projector upside down would allow me to place it closer to the ceiling, intruding less into the space of the room.

 

Any thoughts?
