How do you cool a datacenter in a vacuum? You’d need ridiculous radiators to dump megawatts. How do you service it in space when something breaks?

An individual satellite would not be consuming megawatts.

The radiators are not a big deal. The solar panels required are much bigger. You can just run the electronics really hot to improve the efficiency of the radiation. Nobody is going to get close to those chips so the usual safety requirements don't apply.

You don't service it. Over time the chips degrade and become less useful. Eventually you deorbit it and it burns up. It's a sealed unit, not meant to be replaced.
