Yup -- also Ubuntu, but I'm always looking for new things to try.
I remember some of the first distros which took a stack of old floppies. I used to mess with BSD and FreeBSD too and used it for NAT/Firewalls a long time ago.
We had one Slackware box that had DPT cards and a bunch of SCSI drives that had an uptime of nearly two years. The thing just ran and ran and ran. The only reason it didn't keep going was that we had to move it.
Linux is amazing.....
