do i understand this right ? they are selling only boards . no cables . psu . or cases for the smalles unites? and the newbie user has to figure out himself how to connect this and what to do ?
They are pre-selling assembled boards based on the klondike design (your chips or theirs) that the user would have to connect and what not. They are also selling fully built machines with a case and an optional psu.
are you thinking about https://terrahash.com/shop/ the most exensive one ?
I would like to order something like a big case with psu +1-2 boards and then keep buying boards from then putting it into the same case. hopefully with plug and play difficulty
Yes but not the most expensive one. I did a mini. Their case design is modular and described as plug and play. If they come through then it'll work as you describe.
