I just recently did that same thing in our new house. I wasnt EXACTLY sure which projector i wanted to use and since the ones i was looking at were so diifferent in distance it was kinda stressfull trying to pick the right spot and then making sure that i had everything wired up for whatever I might need down the road. So far i think the house is getting painted this week. Mainly what i did was just place all my plugs in the rear, off to the side somewhat and then put backing in about 4' of the ceiling so i have some options when it comes time to actually mount the projector. I think its kinda hard to really find the perfect spot until you actually get the projector and try it out. Luckly i can also move my screen back and fourth if need be before i mount it.
