Just thought i would let you know about a cool OS you can get for free. It just works. Download the Live disc and boot up on any old pc you have. It installs the base Linux system and a cool front end to make it super easy via HTML to startup and edit your server at any time. You still have access to command line, ssh and ftp. I have been running a craft bukkit server at version 1.6.4 of minecraft for a few months now with no problems.
