Ikea BROR shelving unit modification

Bringing to life an idea that I had for an aquarium rack, made out of components that could be bought from Ikea. Moodboard of sorts; The BROR -shelves are one of the only ones that can withstand greater loads, and this unit should be able to hold 130kg's according to the product information. This would comfortably hold four 19 liter (5 gal) nanos, and the usual maintenance supplies. The cabinets are currently open from the sides, because I wasn't sure if I wanted to "hack" the walls from cabinet doors, or try a different material altogether, like on the FJÄLLBÖ furniture. That steel mesh would be purchased from some local hardware store. This would help wet tools dry more faster in the cabinets and there wouldn't be any risk of water damage, like with a particleboard. The placement of the shelves isn't final, since it really repends on the existsing holes on the unit + the size of the doors.
