Before you reorganize, reduce.

You've got at least two things in those pictures that you don't seem to be using. Get rid of them. Is there anything else you could do without? Any cat 5 that could be replaced with WiFi? Anything you haven't used in over a month but keep it on the desk "just in case"? Any cameras or peripherals you don't use any more but still have the one-off cables plugged into a USB hub?

Be ruthless. Minimize cables as much as possible, then only add back in what you find you can't do without.
