[LAU] Thinking of getting a Shuttle for audio

Hi all, I'm thinking of getting a Shuttle PC to run sound installations from (I need a portable machine for transport). The particular one I have an eye on is this one: Shuttle KPC K4500 Desktop, 1.8GHz Celeron, 512MB, 80GB, Foresight Linux Desktop Computer probably getting a little bit more memory for it, just to be sure. And I'll build in my Terratec EWS88 as an audio card. (One of the reasons to go for a Shuttle, rather than the also tempting Asus EeeBox, but then I'd need an external soundcard, which doesn't seem to be there in lowcost, but many channels, and probably USB; I need at least 4in-8out for the installation). Does anyone have experience with Shuttle machines for audio work? Does anyone have audio experience with Foresight Linux? or should I just take that off the machine, and put Ubuntu or Debian on it instead? Main apps I need are emacs, SuperCollider, JACK... and the machine should run for a couple of months non-stop. (which generally doesn't seem to be a problem with the particular sound installation; I've done it before, and the only cause for shutdown was power failure in the building). Sincerely, Marije
