Server as heating device - how do I do this? (self.diy)

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?

Computers are just heaters that do maths as a side effect, so it makes sense. There's even a company monetising the idea for ESG credits

Two issues i can see are

Humidity in a grow room will be bad for a computer
With modern computers the heat output will in part depend on the workload, so you will need to find a way to make the computer do more work when you want more heat.
