What does the simplest setup look like?

This is the MS-1 (second shelf down, next to SBox Touch) installed in my system. Sorry about pic quality.
Bottom shelf is M2Tech Evo Hiface interface (necessary only because my DAC has no USB input)
and 1TB external drive. The external drive contains all of your music, so the server doesn't have to.
As this server is a mini PC of sorts, I used a wireless mouse and keyboard and connected the MS-1 to my 40 inch
LCD for the monitor (unfortunately I can't find that picture).
In this simple config, the external drive feeds music files to the server via eSata (fast), out of the server with USB to
the USB interface, and from the interface to my DAC thru Digital coax cable.
I used the installed music player as I would any other player as I mentioned with wireless keyboard and mouse.
Mostly to keep it simple and it is what I had on hand.
Did I forget anything HAL?
