A student group from a univertity (UAM - Universidad Autonoma de Madrid) asked me for help to get used hardware for a project.
They want to build a low-scale supercomputer, but it's expensive so they are recycling used components. They don't care if the pieces are 10 years old, because the project is based in complexity, not in speed.
So, if anyone from Spain want to recycle some components or if you're going to travel to Madrid and want to help, you can contact them. Also if you made a project like that you can help with documentation.
To contact, please send me a PM to know how to do it.
