One that has €400 a year or more to spend on powering a 120W server 24/7

[lmm → midasuni]

Assuming it really was drawing 120W, that's about 1000kWh for the year, so €300 at this year's unusually high prices, €150 in a more typical year, and probably half of that will be offset by reduced heating costs.

Parents pay for that, perhaps without realising.
