Cable management is a headache for all, and if unmitigated it becomes a playground for cats. [kws103] posted a project a while ago that takes care of the messy wires for electronics on pull out shelving. Channel bracket is used to house the cables and has been articulated in three places to facilitate the movement of the sliding shelf. For an added touch an outlet was built into the surface to make it easy to unplug and remove the components if necessary. The hinges for articulation use aluminum base plates and rely on rivets as a pivot point, something that might need improvement if pulling the shelf in and out is a common occurence. Add this to the Ikea based solution we looked at in August and your days of electronic rats nests may be coming to an end.
