Returning to hobby - Recommend 20x20 Max Cube?

[Runner]

Hey, guys. Was in hobby for 20 years but just took a 5 yr break. Have a solid wood stand with 20.5"x20.5" usable top and would like to maximize the tank size i can put on it.

Any recommendations for a cube with a overflow/sump in the back? Or one that can be drilled at back/top where i can attach an external overflow to a sump in the base? Already have lights and heaters and other stuff -- just need to figure out what tanks might work.

40G cube would be 21x21x21, so a 35g or below cube would likely be around that 20.5" you're looking for.

fiji sells AIO kits you can silicone in yourself once you find a tank that suits your desired size.
