>These are already existing systems and are set up with Windows, there is not a lot of traffic in the branches (meaning the machine working as the "server" and being used as a workstation won't be stressed), and there is no Linux experience in the company, so that's probably not a real feasible solution in this situation. But thanks anyway. I'd like to get some more experience myself with Linux, but it probably won't happen here.

Not thats its "experience", but Kevin Cully has an interesting blog post about running Puppy Linux (?) on a very dated notebook. Says it screams. I'm going to have to give that a shot.
