You have to understand, that RH9 will take some optimization for an older processor. You can use another free distro though. Gentoo and Debian are great choices for an older computer. Redhat, mandrake, lindows (*shivver*), not so much. This is because they use the latest and greatest Desktop environments (gnome and KDE) both of which have been growing steadily more cpu/memory hungry since your computer was built. Try either debian, gentoo or slackware. This way, you can set up your system how you want it, and optomize it so that it runs fast. The fastest will be gentoo, however, it will take much more time to setup, as gentoo you compile EVERYTHING. Debian will do well on your computer, and is simple to administer because of its excellent packaging system. Slackware would be good, however it takes a fair amount more linux understanding than redhat.
