What do you all thing with a little bit of DIY to this http://www.ikea.com/us/en/catalog/products/S59884824
I would take off the legs and have it flat on the floor. Then the inside shelves of the right and middle would become extra sport on the sides, middle and back (+ I would make Ikea send me extra shelves saying I'm missing oooh 4 of them). The sides then would be almost 2" thick I could go a bit more crazy and have the extra side shelves be shorter so that I could put in extra support at the top. Also the tank would be on the right side leaving some space for decor.
Ya people think I'm crazy! but a friend of my has a 55g on this alone! http://www.ikea.com/us/en/catalog/products/10103088
