I posted in another thread and referred to Dreamspark. Microsoft setup a site for students to get free copies of Windows Server 2008, R2, 2003, Robotics kit and some other nifty software. If you are a student, and your school is a part of the program, you are eligible for participation in the program.

Its been a while since I first made an account with them so the validation method escapes me right now. I don't remember having to send a transcript though.
Enjoy!
