Available time and the honey doo list currently stops me. I have my modem, router, nas and tv computer in a cabinet in the living room and all my camera stuff in the basement on a shelf just under that cabinet. All the HDMI's and ethernet cables are ran through the wall down to the basement and up into the cabinet. I would put everything in there but it gets so hot and don't have a nice way to vent it.
I do have a fan in a home made box tower so the fan is at the top of the cabinet and it blows the hot air into the basement. It works just ok. Due to the cabinet being white, I didn't want to see any fans sticking out of the side. I may just end up putting everything in a cabinet in the basement. I have not decided yet.
