I also have a fobia for cables, even though I prefer them to wireless connections. I used to have a small cabinet beside the tv but wanted to free the space, and as I am to cheap to spend a lot of money on STBBrackets, I found an old cable canal and bought some 3D printed brackets for my devices.
Inside the canal is all the electrical connections as well as a RE*BL for the PS3. I just never got around to cutting the bottom plate the right size, as I can't see it unless I look from over the BV9.
The PS3 gets very hot and lets all the air inside the canal so I've been thinking about putting some fans in the upper part of the canal.
Very neat ! That looks great - and using a 3D printer .... fantastic !
