Server as heating device - how do I do this? (slrpnk.net)

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?

Well, that was my plan when I set things up with an air-to-hot-water heatpump in the same room as my homelab. But the reality is that when it is hot outside, I don't need to run the heatpump (mainly because the solar-thermal water heater is so much more effective). And otherwise the there is no need for cooling in that room.

You can always dump the hot water in an outside radiator if you HAVE to cool the server room to keep the temps down. A simple fan duckt would probably doo fine too. However with the heat pump you can also heat a little hot tub to use outside in summer
