The book Think and Grow Rich by Napoleon Hill. He spends a fair amount of time discussing this exact thing. Wonderful read that everyone should invest a few hours in.

I had a broken screen that caused me all kinds of grief with Gateway. I finally (kinda) got what I had coming to me, though. You can read about it at:

Once you've gotten your spiffy projector built, you might as well attach it properly to the ceiling. I didn't build my own projector, but I did build my own projector mount. I have pictures and more details available. I've built the mount for a couple of different types of projectors, but the design can easily work for just about any projector. Total cost ended up being 2 or 3 bucks for the hardware. I had a couple of old pieces of wood lying around, so I didn't have to buy that.
