I have a Mac Pro 2008 and have a ton of cables behind my desk. My cable management system is very crude. I basically just take the excess cable and wrap them with cable ties and hang them from some nails that I drove into the back of my desk. I have cables for my speaker system, various USB cables, firewire cables, cables for my mic, guitar and keyboard that plug into the audio card in back of my Mac Pro and so on and so forth. I know some people are very neat and tidy and into cable management, I need to be more so, and would like to read or see some pics of what you have done and get some tips if possible.
