For anyone with a smaller amount of chips looking for burnin air cooled boards:
I have purchased 5 BitBurners XX boards that I am wanting to sell. They will require 100 chips.
Order includes a CAN-BUS stacking cable.
Order number is under #500. I believe the numbering started at 300 - so quite early.
I paid 533 Euro. Will take 400, or best offer over 270. You will need to pay shipping. Payment in bitcoin.
