Low voltage wiring ideas for house
I recently had the opportunity to do this on an out-room on the other side of the garage. It just had wood veneer and no insulation, so the gut was pretty pain free.

I'm a forward thinker, but dropping RG6 or Cat 5e/6 into the wall would have been too expensive (and I have no idea where to run it to). What I opted to do was add a low voltage gang and then drill through the top plate. Then I added a screw terminal to the box end (to hold the conduit in place) and pushed 3/4" PVC conduit out of the top. So I have 3/4" conduit in the wall, running into a box. If/when I need any low voltage wiring, I can easily put it into that box without any wall fishing.

A single 10' section of conduit, the screw terminal, the low voltage box, and a blank plate cover, was maybe $5-7. I had to buy a spade large enough to go through the top plate as well.
