Rackmount DJ System - Sound Card?

[kleinwl]

I'm building a Rackmount DJ system for a friend - semi-pro DJ

It's built on a 2U system.
2x250GB Seagate 7200.9 HDDs
X2 3800+
2GB OCZ Value etc.
etc. etc.

The real problem I have is selecting a sound card!
I'm thinking M-Audio's 7.1 Revolution...
But I also see alot more expensive pro gear.
I think most of the pro-gear is for recording etc...
But does anyone have any recommendations?

P.S. I've also been told that touchscreens are really the way to go... does anyone have recommendations for those?

You're leaving to much out

Does the first device in the chain have digital input?
