Hmm, thanks for the fast replies. I'm not sure now of the best route to take.
If we buy machines with a version of windows installed, say Windows 7 Home Premium, can they be used in the school as-is?
I don't know about educational licenses, since our machines are so old (2006) I don't think we're on any kind of agreement.
The PCs I have in mind right now are from ebuyer and Misco, is that a bad idea? should we buy from someone who specializes in selling bulk PCs to education? and if so, who would you recommend?
Thanks again.
