Summary: Don't buy this if you value a bit of peace and quiet. This isn't a case of the projector being broken, this is actually how it was designed! When you power it off, the lamp turns off and the fan slows down but it DOES NOT STOP! The only way to get the fan completely off is to unplug the unit. I understand that the bulb requires a cool-off period, so the fan should stay on for a while, but this fan NEVER turns off.
Summary: A gem of a machine spoilt by lousy colour rendition even by the low standards of projectors generally. The closest it can get to yellow is a mucky olive green. Customer service isn't up to much either (on the basis of InFocus's handling of one machine that was DOA and the colour issue above).
