For those of you who are a little more experienced, Microsoft is giving out a free 120 day trial of their "Windows Home Server" product. This is a newer product geared towards home users with more than one PC in the home. This product was originally released in late 2007. It's an interesting idea, bringing the idea of a computer server in to people's homes. It may not take off for a few years, but it's certainly a forward thinking idea.
Thanks to Saul for the link!
