^ I know what you mean. Been there, wiring up the Testing Lab at Creedmoor State Hospital. (I don't think it's still a hospital.)
Got a pair of those long 12-outlet power strips from Harbor Freight to help "discipline" my own under-the-coffee-table wiring mess. IIRC, they've got 14 ga wiring as opposed to the crappy 20 ga some of them have.
Not much power flow at any one time to my stuff, but what with all the periphs using wall warts, it's getting pretty snake-pitty down there.
