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?

Anecdote:

I have a server running 24/7 in my office, drawing 120 watts average (tested). Office is 10x10. It alone keeps that room 2-5 degrees warmer than the rest of the house. If I turn it off, room equalize to house.

As for comparison, those little square plug in space heaters consume 500 to 1500 watts, and you can see how much th heat.

1 watt = 3.4 btu

Depending on your use case, why not look to reduce power consumption? I've replaced that server with one that draws <20w at idle. That's negligible.
