I use the Apple LCD display to view Front Row. It's big enough to easily view album art, as well as title, artist, album, etc. from our listening area. It is actually quite beautiful! Along with the display, my Mac Mini, mouse, and small Apple keyboard occupy the top shelf of our audio rack.
For remote control I use the small white remote that at one time came packaged with Apple computers. I think it is a cost option now.
The little remote will wake the computer. I only use the keyboard if I am ripping, installing, updating, etc.
