Sleeving, or the act of installing flexible plastic mesh over wire bundles and cabling, has been around for decades. In the not so distant past however, computers were without the benefits of having their cabling sleeved. This led to nasty, messy wiring jobs inside the enclosure which restricted positive airflow throughout the cabinet. This trend has changed, and we now see computer component manufacturers offering equipment that comes pre-sleeved, most notably the power supply with its myriad of cable connections and wires. Not only does this make the product and the final installation of it look great, but is very functional as well.
