Surely a typo with that 2500 MHz...

I run 6.06 quite happily on an 800 MHz machine, I use it as a backup
server, and a spare machine to use when I'm working on my primary
Linux machine. It does well at both tasks.

It has 256M of RAM

My wife runs Centos 4 on a 450 MHz machine with 256M of RAM, but
that's a different distro than what we're here to discuss. It's a
little slow starting Firefox or OpenOffice, but once they start, they
perform adequately.
