That's a typical Chinese commercial mine.

Thanks for posting this, fascinating stuff. I worked as a commissioning engineer at a large L3 data center awhile back. The complexity was staggering. Battery banks, generators, switchgear, evap towers, AHUs, etc. You could almost knock half the building out with a bomb and the other half would hum along without skipping a beat. Between two and three sources at each bus, all trickling down to the data center rooms themselves. Just testing all the systems took months. Hundreds of millions of dollars from start to finish.
But look at what these Chinese guys are doing. Open air ventilation, cheap rack mounting, etc. Budget, budget, budget. It works. There's no way to compete with this in "developed countries" (lol) where you can't put up a tool shed without a building permit and environmental impact study.
On another note, it turns out that the problems data centers and miners encounter are exactly the same for large-scale indoor cannabis growers, except for tighter environmental controls in each rooms. This is becoming a big business in Washington and Colorado.
