The analysis has zero redundancy for either servers or support systems.
Redundancy is a small issue on Earth, but completely changes the calculations for space because you need more of everything, which makes the already-unfavourable space and mass requirements even less plausible.
Without backup cooling and power one small failure could take the entire facility offline.
And active cooling - which is a given at these power densities - requires complex pumps and plumbing which have to survive a launch.
The whole idea is bonkers.
IMO you'd be better off thinking about a swarm of cheaper, simpler, individual serversats or racksats connected by a radio or microwave comms mesh.
I have no idea if that's any more economic, but at least it solves the most obvious redundancy and deployment issues.
