Do you still keep them at home, did you rent warehouses, did you put them in server racks and move them to data centers, or are you using any other solution? What is the most beneficial way and cheapest electricity long term these days?
I keep it at home in the special room where I work, the room has been designed to build a mine.
For the power supply, I use solar panels combined with my own assembled electrical converter, so that the power generated can be maximized.
