The present invention relates to one of two embodiments, which provide a refrigeration jacket that can be placed over or surround electronic equipment, such as the tower of a personal computer, a plasma television, or a video game console. The primary embodiment of the invention comprises an extendable jacket or cabinet that has a plurality of cooling coils running throughout the jacket or cabinet. The invention also requires a refrigeration compressor and condenser, an electrical cord, and a closing means. When in use, the cooling coils refrigerate the surrounding air, which in turn cools the electronic item in use. The result is an electronic item that can run for pro-longed periods of time as well as higher speeds due to the removal of heat associated with the computer's processor. Other embodiments include a computer game console embodiment, a plasma television embodiment, and a non-expandable computer console embodiment.
