This is one I built a few years ago. Got it from DIY Projector kits.com It has a 17" Samsung in it and can get the picture up to 10'x15'. I like it better on my blow up screen though and it is 9'x12'. I use it for movie nights for the city and for the superbowl. Working on the home theater now and going to build a new one same size better LCD or a smaller one. 400 Watts
