I recently took down my 20G aquarium, and am looking to rehome it. It's an interesting tank because it's drilled in the bottom pane for a closed loop and has a glassed in overflow for incorporation of a sump. The nice thing about this setup is it eliminates the need for any internal powerheads.
The aquarium could use a good wash, but is otherwise in good shape. Glass is scratch free on the viewing sides
Here's how it look before being drilled for a closed loop:
Currently, view from top down showing the 4 openings (2 in the back, 2 in the front):
