We really like this little project. You don't need many fancy things to start managing your cable mess. Usually, some tie-wraps and a bit of smart thinking can get you started. We like how this build uses a cheap coat hanger to get the job done. The fact of the matter is that no one will see it, so it doesn't really matter that it's cheap. It will be nicely hidden away.
Antoine from BitsOfMyMind has come up with a very simple way of using an inexpensive Ikea coat hanger rack into a really nifty streamlined cable management system. He originally came up with this idea when a $10 cable management add-on from Ikea was no longer available. Antonius coat hanger to the underside of his desk, using wood screws. He also used a hollow tube so that the hangers were safe. The best part is that the Antonius coat hanger costs $5. However, if you have trouble finding this coat hanger, don't despair. Any similarly made coat hanger will do.
