Just reinforce each shelf and each level with reinforced L brackets the type found at building supply shops,
My 10g is in a simple box, look at what the jewel Rio cabinets are made of mdf, or even chipboard with a melamine cover,
Cabinets built by most members of these forums are often over built by there ego,
As long as the edges and corners have a support running to the floor, it will hold,my do it for a living, some of the stuff IV seen on some of the stupidest looking stands would shock you, but Gravity is our friend
You have two options, running 1x1 ad own the middle of all shelfs and side woods, so making a box in each level, would reinforce it, and a new fibber board back
Job done
