Hi,
Thanks for your questions.

They are currently hosted with GND in NL if you are interested to keep them hosted with them, which is most probably possible, you might want to get in touch with them regarding their latest rates and running cost.

I am open to all reasonable offers, price/delivery can be further discussed in PM

Yes you are correct, all miners that have a 2 instead of a 3 under Boards mining have a defective board or enough dead chip that I haven't counted the board as a valid one. It might be something fixable but given the fact that I am not on site it is hard to troubleshoot. I can provide miner status screenshot of all of them to potential buyer for due diligence.
