I am interested in re-wiring my entire house's low voltage wiring. I want to do coax, audio, CAT-5, telephone, etc. etc. What good sites offer diagrams and tips for a project like this. I was thinking of installing PVC conduits to each room all leading to a central hub to make it easier to fish the cable. I want to make this obsolete proof, at least for the next ten to twenty years. What advice can any of you offer?
