I will be getting a 50" Plasma TV. Along with that I need a space to hold the center channel speaker, receiver, DVD player, and VHS unit. The TV will be positioned diagonally in a corner. I plan to build something like this as seen from above:

Actually three of these are shelves, and two sides with dadoes made in a Shaker-style. The top shelf should be about 4 feet high. My issue here is the span. The 3/4" ply shelves are 17" deep with a 1.5" solid wood lip on the from and back. The TV weighs about 100 pounds, receiver 30 lbs, VHS 15 lbs, speaker 20 lbs, and DVD player 15 lbs. Since this shelving unit will be holding about 4 grand of equipment, this must be sturdy. The sides will be against the wall, possibly with fasteners (any suggestions for fasteners?)
