Last time these folks were mentioned on HN, there was a lot of skepticism that this is really possible to do. The issue is cooling: in space, you can't rely on convection or conduction to do passive cooling, so you can only radiate away heat. However, the radiator would need to be several kilometers big to provide enough cooling, and obviously launching such a large object into space would therefore eat up any cost savings from the "free" solar power.

Even beyond cooling, just getting all the hardware up there is extremely costly, and for what benefit over ground based DCs? The cooling is the ongoing problem but the cost of lifting it there obliterates all the other problems, IMO.

Space X thinks they will reduce the cost by 90% with Starship, so they are probably calculating off that.

On the linked page there are animations using Starship.
