I actually use the good old heavily modded G4 Cube as a music server for Front Row and iTune. It is connected to my Pioneer plasma as well as to a 7' LCD screen. I have everything set up to switch back and forth between the two using my Harmony remote control and the Logitech DiNovo keyboard for the occasional internet navigation. The reason I am setting it up this way is that I don't want to turn on my plasma all the time. I also set up the screen saver such that the 7" LCD doubles as a digital photo frame when I am not accessing the Cube for music.
I would love to use the iTouch as a remote for my system but it doesn't do infrared, so that's a no-go.
