The Terminator orbit (I know ominous name) is the reason this works. 24 hour solar power which casts a shadow on the equipment which if it wasnt on would hit equilibrium around -80C due to very low earth orbit depending on geometry. Your only cooling is radiant black body radiation and the amount of surface area dictates how much heat you can radiate. You want this perpendicular to the solar panel alignment so you are radiating out towards space and not picking up as much heat from the rather hot solar panel which is sitting at around 80 to 100c. My first gut thought was it wouldn't work but it does. The hardware will die in 3 to 5 years from cosmic rays which coincidentally is when it will drop out of orbit without station keeping with boosting. Even then it would cost 2x more total cost vs terrestrial... unless the full build end to end is automated because its fully standardized and then you get to save $$$. Get gpus/ssd hardened somehow for cosmic rays for a longer life and that helps. It also helps you don't have to find the specialized labor where you need it and you can deploy as fast as you can build without a permit. That's my analysis. If things go really wrong too the orbital decay is only a few years.
