Antminer Z9 Mini bought directly from Bitmain.
Stable overclocked to 750 MHz, hashing over 15 KSol/s.
Running on lower frequencies to minimise noise.
Suitable for home mining, noise is tolerable even in a living room.
Runs perfect, no issues.
The back has been opened for cleaning so the blue sticker is broken.
The power supply is not included in the listing.
