Now, far it be from me to rain on the SBS parade, so instead I will offer you some additional resources should you be so inclined; setting up an Ubuntu server (aka Ubu) offers a variety tools that in many cases are unique to the *nix platform.
You can take one of your worn-out old machines, and give it a new life as a handy utility server. For some folks, the whole subject would be an exercise in technical esoterica, so I don't belabor such subjects.
So once you have your new Shiney up and operational, give me a shout if you want some help tinkering.
