Nice Howto on Setting up your own Personal Web Server

Lifehacker has a nice howto on setting up your own personal web server, giving you the ability to do things like stream mp3s from your personal collection to work, set up a web based shared calendar for your family or give yourself quick access to your personal files from anywhere you've got net access. The system is password protected of course, but it is built on a windows box, so beware and be patched.
