In case modding, the term wire management is used to describe the miracle of turning a mess into a masterpiece.

You start with tons of unsightly wiring, and you relocate, conceal, and confound the stuff until it starts to look tidy and organized. It’s a time consuming process, but it is critical if you want a great looking case. Unfortunately, no matter how hard you try there will always be some exposed wiring inside your case. This is where the sleeving comes in handy. PSU sleeving is generally made of a nylon type mesh tube that is slipped over your wiring. It comes in an assortment of colors and can even be UV reactive to help make any exposed wiring become as eye pleasing as possible.
