What is the cheapest you have seen it?I am gonna be doing a whole new build and I am trying to get it cheap as possible.
Are you a college student? If so, many colleges, if they're part of the MSDN Academic Alliance, offer Vista and other MS software at major discounts. If you're in a computer related major, you might get Vista for free.
I'm a CIS major and my college is part of the MSDNAA. So I get Vista for free That's the cheapest I've seen it LOL!
