or just have a large reservoir, severely overcool the cpu and cold-brew the coffee

Its objectives lie elsewhere.

Digitally enhanced coffee as fungible tokens. “Decaf” for short. What could go wrong?
It probably wouldn't be great for your CPU, because the temperature required to properly brew coffee is hotter than you really want for your CPU. But maybe get the water to 80C, and a secondary heater after that.
And have a reservoir large enough to replenish the closed loop circuit when you press the button.
I would set something like this up in my house if there was some kind of decentralized processing company I could register with.
What is probably more feasible is to save on heating costs by heating your apartment partially with your computer.
That is pumped so it cools down the water going through the computers.
It has gone through several revisions plus complications with wanting to heat up solar panels too.
I doubt the extra piping and infrastructure is anywhere near worth it, but I sometimes fantasize about an experimental building that was designed from the get-go with a single integrated heat loop that all the major appliances were plugged into, and how that might look. Seems like the sort of thing that could be tried in a much more confined space such as for an off-grid RV.
I wonder. Infrastructure investments tend to have absurd payoffs. For example, my solar energy equipment has been generating profit for years.
In my country 5 kW electric showers are common every day items and they add up to a huge chunk of household energy consumption. Switching to a more efficient water heating system has been on my mind for years. If I can use my home server as a heating element, so much the better. Could even use free CPU cycles to mine Monero on it. A solar powered cryptocurrency mining home serving water heating computer. Wow.
I also think a lot about the heat my air conditioners constantly pump out of my house. Seems like a waste to just throw it out of the house like that. Ideally it would be stored so that it could be used to heat other things later... To me it seems like it should be possible with enough integration.
In contrast to the RV proposal, maybe a better option could be something like a boutique hotel, where you’ve got 100+ showers happening every morning, so having a giant cistern of hot water that you dump all the waste heat from AC, fridges, and freezers into makes a ton of sense.
Nailed it.
However, there's a fairly straightforward way to get halfway there: You can run a standard heat pump hot water heater and put the computers in the same room with it. The computers will heat the air, the heat pump hot water heater will cool the air. Won't be as efficient as a closed loop system directly connecting the computers to the HW heater but you also won't need to worry about whether the heat production and consumption are balanced.
I really want to get one and pipe all the exhaust from my homelab to it.
New house builds often include one to run domestic hot water and under-floor heating for bedrooms and such. The downside here is that you probably also need an air-to-air heat pump for cooling in summer, and now you have two expensive heat pumps, and a whole extra set of pipes running around...
Unless you've got a monster ML workstation under your desk or a crypto mining rig in your garage, that surplus heat isn't especially useful and isn't really worth harvesting. A typical desktop PC only dissipates a few tens of watts at idle or a few hundred watts under heavy gaming loads, versus many kilowatts for a typical domestic water heater.

It could get to 60°C which is a bit low for coffee but was great for mulled wine

Share and enjoy!
Don't worry, I'll run an Electron app.
really stupid arrangement. slurry from the coffeemaker clogging your rad and cooling block, not to mention corrosion
better would be RO water -> pc -> coffemaker no rad needed
I used to manage a scientific supercluster, heavily laden with GPUs. We were constantly consuming about 60kW of power. These GPUs were happy to run at 85C, which from other interests I knew to be the temperature where alcohol distillation occurred. I always wanted to install a heat exchanger and distill fuel with all of the waste heat.
