A local group I am involved with is offering a computer lab to a community centre. The idea is to run Ubuntu with the education version running terminals on old Pentium 1 and Pentium 2 computers. The donated ThinkCentre will be the server for this small lab that will allow an upgrade of the community centre's computers. This is being done for a community centre in a small town near, Ottawa, Ontario Canada.
Here is the link to the basic information about this version of Ubuntuhttp://www.ubuntu.com/products/WhatIsUbuntu/edubuntu.
