I see so it's not really about the coffee.

Coffee is the sats flow but I envision it growing to more.
I also want an immersion mining setup to heat the water. On display behind plexiglass for customers to see.
The idea for heating the coffee water with miners is pretty clever but the operational temps of miners (0C to 40C) are lower than the optimal brewing temps (90C to 96C). Though you could use it to preheat the water with the miners and the setup would be a super cool visual.
Good call on the heat. It would just feed the water heater, not direct to brew
Could have a server room in build out for things.
Could host events in second floor area or more generally serve community needs.
Trying to determine the value of third spaces.
