I'm actually surprised that Bitmain's flagship product is a 1,300 watt device that costs less than a decent used car. If I was Bitmain, I would be building "enterprise class" mining systems that would be self-contained units with 200 S9 machines, pre-wired and pre-configured, with dedicated cooling systems, requiring 1000 amp electric service. I would think these would be much more attractive to people wanting to do cryptomining on an industrial scale.
Imagine United Airlines converting their entire fleet to the same number of seats worth of 8 passenger Lear Jets. That's what I see when I see a photo of a rack of S9s or open frame 8 GPU ether rigs... a line of 50 Lear Jets trying to do the job of an Airbus A330... But, a photo of 200 S9s taken thru the door of a refrigerated shipping container, would look (to me) like a photo of the rows of seats in the Airbus.
I agree, weed pods was a goofy idea with no chance of success. But I think Bitmain would have much success selling mining pods...
