Looks to me like the end of a lot of small mining ops.
It is 3 phase power which is more industrial than 240.
I wish specs got released.
10 k-watts and 500th each?
or 18 k-watts and 1 ph each?
In the pics I see 4 units in a rack with 4 PSU's per unit and 12 boards.
Lets assume boards are comparable to the S19 Pro -> 37 TH/s at 1050 watts each.
444 TH/s and 12,6 kW
total rack about 1.78 PH/s at 50 kW per rack
50kW is already achieved in HPC clusters with watercooling, so that sounds plausible...
Sounds great, hopefully the cost is acceptable
