I had to run all the cables for all the machines in our classroom recently and you know how messy it is with all the various cables needed to make a PC run. Last time we used zip ties, this time we tried a product called Cable Zipper that I've been really happy with. The link is to Amazon, but we bought ours at the local OfficeMax, $14 for 8 feet of it, but it goes a long way, and it's reusable.

I've haven't tried this decluttering solution yet - it's on the agenda to try it at home along with my favorite peg board hooks.
