Our CPU Holders are designed to efficiently and securely hold a computer in a wall or side mount configuration. The CPU Holder is made out of strong steel material and finished in a durable matte black powdercoat finish for a long lasting, good looking appearance. This computer holder is designed with top and bottom flanges on the open front facing side of the mount that secure a mounted CPU to prevent tipping while allowing for maximum ventilation.  The four holes cut into the top flange of the holder can be used for attachment of accessories if desired. The CPU Holders come in different sizing options for variety in specification. When determining the right holder for your computer, we suggest choosing a holder that is no more than .5 inches on the vertical and .5 inch on the width dimensions larger than your machine.
