Microsoft has just released a program called Evalu'08, where you can evaluate Microsoft Server products and win a server for your home. All you need to do is download and evaluate any of the 3 products which Microsoft launched recently. Download a free trial of any of the launch products or take a virtual lab and be entered for a chance to win great prizes.
The program is educational in some sense if you consider marketing speak to be informative. You can attend the virtual labs for a host of products and win the prizes. Alas! the rules state that its open only to legal residents of the 50 U.S. (includes D.C.) 18+ employed in an IT or software development role.
The prizes for the lucky draw is either a Zune, if you evaluate 1 product; an Xbox360 if you evaluate 2 products or Windows Home Server if you evaluate 3 products. The contest page requires you to have Silverlight installed and you need a live ID to signin.
