If you're going to go the route of using an LCD i'd say don't even bother building an entire cabinet. Just build yourself a full size control panel and make the screen something that either wall mounts or attaches directly to the CP. Or, make it even EASIER and build a full size CP, put your computer bits inside, then use TV-out to connect to any S-Vid capable television. That would give you ultimate portability and a very small, light package. I may end up doing just this sometime in the future. I'll still keep my full size cabinet, but this would be great for gaming on the big screen (i actually had my current CP setup this way for a few days while i was doing work on the cabinet itself).
