I've got a bulit-in wall shelf that is part of the room. I have it wired (electric + ethernet + antenna coax).
All of which supports Channels in some way (and does many other things too).
Mostly older stuff, but I just recently bought that QNAP at the bottom of the rack, as a replacement to run Channels instead of the DS916+ at the top.
The QNAP was a great choice. I had avoided QNAP for a while thinking that they were risky, but I know how to secure a network. This thing is fast and works very well with a large library. I like the interface too. And it looks great in the rack.
