MOS Magnetic Cable Organizer
An unfortunate side effect of being a gadget nerd is that you start accumulating lots of cable clutter around your work area. They get dropped all over the floor, left around your desk, or mysteriously disappear into the ether. There are many methods for managing this clutter, but one of the nicest-looking ones I've come across is the MOS Magnetic Organizer.
This sleek little cable drop will keep your cables in place and the aluminum version makes a great desk companion for your Mac . Not that you have to keep it on your desk, since it includes a mounting ring for potential wall placement. It also includes three magnetic cable ties in case you have cables that don't respond to the MOS' magnetic field.
If the $40 aluminum model isn't your thing, there are black and white models available for $20 each.
