a front projection system is an lcd/dlp/crt projector with a drop down or fixed projection screen. In your situation you would be best served by a drop down screen in order to still have access to the electronics behind the doors. AVSForum.com is kind of like the audiogon for video stuff most questions can be answered there...I don't know enough about them.
thanks for the info on the HSU...I'll probably look into getting one down the road.
