[LAU] <= 500 euro linux/barebones laptops for audio?

Greetings all, I'm planning on ordering a laptop this weekend for writing music and such while away from my desktop. Now, while I'm budgeting for around about 500 euro, my gut tells me that I won't be getting fantastic hardware for that money. "But wait Andrew! We don't know what you'll be using this for!" I hear you say, so I'll just quickly outline what I plan on doing: In short, I don't need a tremendously amazing audio card, with high quality mic preamps coming out its wazoo, as I'll be working exclusively in the digital domain (linuxsampler/bristol/zyn/yoshimi/ams) via an externel midi controller. In addition to that, I'd rather not have a windows OS pre-installed on it, but rather it be powered by linux from the get go (ideally) or just a hunk of pre-assembled hardware. RAM I guess is a moot point, the more the better.... but 1GB would be a minimum.. Should I provide more info, or is what I'm asking outside the range of what's commercially available? (I dread the thought of having to build a laptop from scratch, to be perfectly honest) Andrew.
