Abstract: The computer cover is a specially constructed cover for computers adapted to cover the entire computer case or monitor, including the vents and fans. The cover is constructed using a durable polyester material containing a plurality of uniform micron openings. The material may be treated with a hydrophobic process. The resulting material is water repellant, yet filters out dust and debris without detrimentally hindering airflow. The computer cover has a sleeve for wire and port protection in the rear of the computer and a flap positioned to allow access to the computer disk drives. The sleeve has a strap for tightening the sleeve around the wires. The flap, when closed, completely seals and protects the disk drives.
