There's nothing here you couldn't do with a few lengths of masking-tape and a ballpoint pen, but as the whole point of cable management is to be fast, neatly hung and leave a good-looking floor, we'd recommend these sweet, candy-colored caps from Dotz.
There are two kits, the straps, and the "Dotz Identifiers". The straps are color-coded cable-ties which can be undone and reused, and come with push-out paper inserts to let you keep things further organized. The Dotz dots are even more ingenious and clip to individual cables so you know just which power cable to unplug, or which USB cord runs to which widget. Better still, both packs cost just $10 apiece: The cable-ties have eight pieces and the cable-buttons 10.
