Is there any way for you to move the storage containers off the bench (if they are there permanently), I found moving my parts storage off my tiny 120x50cm bench/school desk/bedside table very helpful, allowing me space for an analogue scope, laptop, small PSU, multimeter and laptop, with some space for working. Also, I would recommend moving the big (deep) PSU to the end, where it is less intrusive to your work area. These are just ideas, and I suggest constantly changing the setup for the task at hand, as it takes five minutes, but improves productivity tenfold. Just a thought.
EDIT: sorry, didn't see the posts after your OP, maybe try moving the small test gear (multimeters etc) to the side so you have a central workspace? Anyway, don't sweat it, your working space is 5 times more than mine! I'm curious, what do you (and others) do about test, USB leads and cables?
