I found this site when I was trying to get a copy of 2003 server last week, one of the torrent comments was "its just a dreamspark edition"

anyhow.. if you're a current student, you're eligible. I just got my login today. Not a huge amount of software, but it's free and legal.

Applications include :

Windows 2008 server
Windows 2003 server
Visual studio 2005
SQL Server 2008
XNA Game Studio

then they have some visual express edition titles which are already a free download. Downside is that it looks like they're x86 versions, so I'm not going to install 2008 server as my OS since I have 8gb of ram.
