Developers and users take note: Microsoft is currently running a promotion for their new Home Server operating system, which involves a $50,000 prize for developing the coolest add-in. In order to make this contest possible, Microsoft made Home Server RC1 available for free download for a limited time.

Keep in mind, RC (release candidate) is not the final version of the software, but is deemed stable enough for a release to the public. So if you are a development or PC enthusiast, be sure to check out this new OS and enter the contest!
