The back of my desk is a huge tangle of cables, you wouldn't believe it, with or without self-adhesive cable ties, but at least it's no longer a rat nest that used to be. It worked from really scary and impossible to still scary but well within reason so many cables minimal fuss I'll try to post some before and after pics when I get a chance.
