I know not everyone likes the "industrial" look but as far as putting in lots of outlets, I insisted to my electrician (my father-in-law) that I wanted junction boxes and conduit mounted on the outside of the finished walls. I mounted the conduit and my compressed air piping on Unistrut so there wasn't even any need to bend offsets. Straight pipe into the boxes and straight out. Went up 1 size conduit than needed so that if I ever needed to add 220v outlet or whatever I could just run the wire through existing pipe. I love it.
