If you have never set up a linkux box before I would suggest a simple distro to install. Mandrake was my first linux distro. It is easy to install. You can grab a copy here: http://www.linux-mandrake.com/en/ftp.php3. There are other distros that I feel are much better but are harder to setup. If you want to really jump in to linux and build a system completely from scratch try either Gentoo (http://www.gentoo.org/) or Slackware (http://www.slackware.com/). I hope that helps a little.
