I bought this to secure some networking equipment. Unit was easy to assemble with a power screwdriver and the instructions were easy to follow, as the parts had corresponding labels on them. I didn't mount the box on a wall (maybe later), but have it on a shelf and it looks sturdy and clean. Seems to have enough ventilation so as to not cause overheating problems, but it really depends on how much equipment is stuffed in there. It came with plenty of extra screws and brackets to mount more equipment on the racks. The vent holes in the top are sufficiently large enough to be able to put exhaust fans if cooling is needed. Overall, this is a really good value-priced equipment box.
