Yeah, I do a lot of recycling here, what with our tiny budget. It would
have to be something reliable, though, if it's going to be our primary
time server. I'd probably reserve a couple of our old Dell Dimension XPS
PIII machines installed with Fedora 9/10.
You might be surprised to learn what's still being used in a production
environment these days. We have an old VME chassis running AT&T Unix
System III. We also have recycled Gateway 486-DX2 machine doing internal
firewall/routing between DSL links. Don't even get me started on the
real-time OS Unix variants.
