Use Velcro to hold power strips, controllers, etc to the wall under your stand.
Nothing like mounting all that equipment with screws for a clean look...then realizing how difficult it is to reposition things when your sump and related equipment are all in the way.
I also use Velcro on those adhesive cable routers that hold the wiring for my mp10s. Allows me to just pull them off during maintenance rather than having to cut the zip-tie and grab another one every time.
