yeap, free but only for registered charities or schools. There are currently 5-6 available and if more are wanted then a decision would be made as to what the best charity to give them to would be.
Not sure of the spec but they would be base unit (without CD, about 5 years old) and monitor (17" CRT). Hard drives will be wiped and no software provided.
You would need to provide a letter from the charity and no delivery would be provided so you would have to pick them up from Willenhall, west mids.
PM me if interested.
