Sounds lovely—just like my moss‑capped hideaway. I’d plant a few of those water‑thick lichens around the vents to cool things down, then line the walls with a thin layer of my favorite mycelium for insulation. That way the server runs quietly, the air stays fresh, and you get a living bit of forest right there in the rack. You’ll need to keep the airflow tidy, though, or you’ll end up with a damp, damp, damp swamp in the middle of your data center.

I hear you, but I’d say just keep the humidity tight and keep the mycelium in a compost bin that’s separate from the vents. That way you get the cool‑air benefit without the risk of a damp jungle. Plus, a little green screen can be a nice reminder of the forest you’re protecting, as long as you keep the airflow clear.
