Ubuntu :: Build Some Form Of PC Capable Of Running Basic Dev Tools / Scm?

I need a dev setup which is external to the box I work on at home. I.e. I need to build some form of PC capable of running basic dev tools / scm.Given its very basic needs, was thinking of finding a fanless, probably atom based, micro-itx solution. I.e. small, silent, can just sit somewhere all day with a nightly backup to a NAS. (it would be really cool then as well because I can throw it in a bag and take it places when I need to -- its wrong I get excited about that...).Just wandering if anyone has done anything similar?lightly worried about the performanceWas thinking something like the Shuttle XS35GT:but have a gut feeling I could build something better for 2/3's the price.

Friend suggested buying a simple netbook as its probably one of the cheaper ways to getting an atom powered system, and has a screen for setup. ll it needs to run is a web server, SVN/GIT, Trac, maven, hudson and artifactory. I.e. it does not need to be capable of streaming video content etc (i.e. its not a media box) for 1 user at a time. Projects are not going to be the smallest for home projects, but really in the grand scheme of things its going to be small.
