I've purchased two of these cabinets for two different jobs and I'm very pleased with them. The cabinets are well made and solid. The side panels are removable as is the front, glass swing door. The cabinets have ventilation slits on the sides at the top and bottom. Removable cable access plates are located at the top, bottom and back of the cabinet. The mounting bracket is easily mounted onto a backboard and the cabinet is then attached to the bracket. I had help installing the first cabinet but was able to install the second cabinet by myself. Will definitely be purchasing more of these.
