Sub Zero F is seriously cold! But for most climates there is some advantage. 40F is pretty cold. Take somewhere not particularly hot like London - most of the year it will be warmer than that.
Although in the UK most people use gas to heat their homes, because its cheaper. I worked out once that gas and heat pumps cost the same in the end for the amount of energy. Although what I love about heat pumps is how quick they get a place warm compared to radiators.
Granted heat pumps need installation, or you can probably run a tube out the window with one of those adapters.
It's a silly hypothetical discussion, because for the price of this mainframe you could get a heat pump and a set of solar panels and a battery storage, and have some money left over for some Hawaiian shirts to wear once you've heated the place up.
For financial efficiency (environment be damned) a set of crypto miners would be better than either the mainframe or the heat pump.
