New SC Aquarium 100g Reef build

[JCSReefing]

I am about to begin my build for my 100g SC aquarium. I will be placing the tank up against a wall which if i drill/cut out part of the wall, it will go straight into a unused closet. I am thinking to run all my apex wires, sensors, probes and what not from my sump thats in the tank stand through the wall and mount it all cleanly inside that closet. Has anyone ever done this? Also, still up in the air on running the sump in that closet as well and plump the drains/return from the tank, through the wall into the closet and put the sump in there. If anyone has any input or has knows anyone who has done this and has pics it would be greatly appreciated.
thanks,

Put the sump In the closet and the apex under the stand and then put all the extras for the tank under the stand for water changes nets etc

Anyone know if I can paint 1" pvc pipe and then glue it without sanding the paint or does that effect the bonding of pvc cement?
