I hope you are aware the Hydros need 3 phase 380V power... Indeed i saw an aftermarket water cooling solution for a single unit half a year ago, Is it worth it? I'm not sure... Of course they want you to buy the container for the miners as well. Getting a single unit is possible in the second hand market, again, i doubt its worth the trouble. Just get two 125T units...
He will come back with how he can convert something in his house to a 3 phase connector 380v breaker/plug and just implement it with his custom watercooled solution to work in place of the AntSpace solution they were designed for. Still spending so much more to make it work but "Hey he will save that $1 in power" instead of just understanding what everyone is trying to say that it's cheaper and easier to run 2x 125T units. To each their own I guess?
