Looks great Zaphod, very tidy and well done. One suggestion that might make your life easier would be to look into a Boss NS-2. Not as much for the noise suppression (which works well) but because it doubles as a power supply. You can run a single wall-wart adapter to the NS-2, then it has a cable with multiple male plugs that can power all of your Boss pedals.
But hey it looks like that pedal board can handle all of your wall warts plus those from 2 adding machines, a hair dryer, an inkjet printer, computer speakers and an answering machine! Now THAT would be a full-featured pedal board.
