Data centers ultimately need to provide power and remove heat. Solar might be a little easier for power in space, maybe, but heat is an absolute no-go, stop, this will never ever work. You can't engineer your way out of the fact that space is a vacuum.

if the thermal radiation panels have ~3 x the area of the solar panels, the temperature of the satellite can be contained to about 300 K (27 deg C). Ctrl+F:pyramid to find my calculations.

I looked, and you outlined a solution that would be hard to achieve in a vacuum chamber on earth. Now we're going to launch it into orbit and it will work great?

Building data centers in Antarctica with nuclear power would be easier. And still way harder than necessary.
