Here you go. General measurements for front to back, I couldn't put my tape measure flush with the speaker boxes, but you can gleam the idea.
Any pics of your current setup? getting the image to the bottom should be easily achievable with some fiddling, check my youtube link on previous page, its far from central though ><Anyone else's screen frame ever-so-slightly warped so it pops out on either side? If so, any tips on getting it to stay put?
All the Megalo love on here lately has me working on mine. Got a mount for the projector and some rough idea where it should be mounted, just need a few blocks of wood to mount it to.
I think something's in the way of the screen though as I can't get anything to show on the bottom 2" or so of the glass.
