thats the idea. You'd be able to put the "top" (now the front) on, slide it down an inch, and lock!
What i'm most curious about is (1) if the glass is strong enough to support itself and (2) air vent options. I was thinking if I use plexi glass or some kind of clear plastic, i could drill maybe 3 columns of 10 holes on each side, so a total of 60 holes. Anybody think it would be enough?

The top dashed line and bottom underline part are the sliders on the lid. The middle line is the slider on the tank. The (space) is part cut out so you can lift the lid off.
