Good tip on going into the attic/under the roof. I'll have an attic in this place so maybe that's the best option to run the wires.
I've patched drywall a handful of times. I'm good enough at it that I can get it done it just takes me longer than it should hahaha.
In terms of what I want... It's going to be 2 work from home stations/desks. These won't move. A gaming setup (this is what I want hard wired the most).
But I also want to have a drop in each bedroom - just in case.
