The coax cables will be 50 feet each, each going to a TV.
Currently, the cable comes in and is split in a closet. I'm going to hook in the cable modem from inside the closet where my networking gear will be (2 cisco 2620 routers, 1 Cisco 24 port catalyst switch). I'll cat6 Ethernet out of the closet, so the coax from cable source to the actual cable modem will probably be less than 3 FT at most.
The longer coax cables will only be going to cable boxes (I am _assuming_ these require less juice than the cable modem...?)
The Ethernet will be running to my office and to behind the TV Great
idea on the speaker-wires, I'm not sure how the heck I didn't think of that! I used to have in-wall speakers in my old place, I actually prefer having speakers that are somewhat less permanent though
If anyone else has any other thoughts, suggestions, or things to remind me of I am all ears...errr...eyes
