I'm working on a project to use cool a server with watercooling and use this heat for my house. I'm planning to cool the CPU and memory (maybe GPU). It will host my own websites as well as some services for friends.
Issue 1: home bandwidth is limited.
Issue 2: no calculations = cold house
1: Are there any server tasks which are CPU intensive, but don't require to much bandwidth? (Game server? Video editing?)
2: Folding at home uses spare CPU time. Are there any services like this that will also generate some money? I have looked at Threefold Initiative and Golem, but I'm not sure if you can turn that off fast when a web request comes in...
