I got this GearBox to fill a space in my garage that was a little too small for the 30" cabinet.  I was worried about about the sturdiness of a cabinet that required some assembly compared to the 24 and 30" GearBox's that come pre-assembled, but that worry was for nothing!  The GearBox was easy to assemble; the interlocking tabs, screws, and bolts all tightened up into one sturdy little cabinet.  The magnet door latches built into the shelves was a nice touch for a long lasting design.  I'm very excited about adding the storage space to my garage!
