Oh Demonsgate:
The sides and top are cut to hang over 1/2" on the front and back. That's so the back panel will sit 1/2" inside the others and eliminate much light leaks. Any further light leakage can be dealt with with small strips of facing or crown molding, mounted to the rear piece but made to overlap the sides. I'll get some pics of my rear panel for you when I do my 1 week flowering pics.
