Description from ebay .
We bought a large quantity of these computers a few years ago unfortunately we got less power supplies than computers. We have now sold all the ones with power supplies. They are in clean condition and have only been used for a short time and are likely to be working ok. I am not able to test them because I don't have any power supplies so they are sold as is with no guarantee in lots of 4.
Postage is £8.59
