So I have this silly idea/longterm project of wanting to run a server on renewables on my farm. And I would like to reuse the heat generated by the server, for example to heat a grow room, or simply my house. How much heat does a server produce, and where would you consider it best applied? Has anyone built such a thing?
You could probably mod a water cooler system to connect to a water to water heat exchanger like this: https://www.heata.co/
In general, like others have said, lots of humidity is bad for the hardware, you will need to separate this somehow. But heating a small grow-room with an extension of a CPU water cooler might be possible.
