Sandra is a PC server, running Ubuntu Linux. It’s located in a shed. The ambient temperature is around 0-1 centigrade currently, so the temperature is pretty low. I’m running tests and seeing how she fares. There’s approximately 1250 watts of heating power located in the 15 cubic meter surrounding the machine. 250 watts comes from the power source of the PC, and 1000 watts for a coffee pan 🙂
I’m working on the insulation to make the environment more PC friendly.
