Bitmain Antminer S21 Pro 234T in excellent working condition. It is over one year old, has been used regularly and continues to operate perfectly. Two identical units are available.
The original factory fans have been reinstalled. Each unit also includes a complete upgraded ventilation package consisting of:
• 10-inch AC Infinity inline fan • AC Infinity silencer/baffler • Reusable air filter • Two custom 3D-printed airflow shrouds • Original Bitmain single-phase C21-to-P13 power cable • Original shipping box
Originally purchased for approximately $8,800 each, plus roughly $900 for the AC Infinity fan and additional accessories.
These machines consume a significant amount of electricity and produce an enormous amount of heat. The buyer is responsible for confirming that they have the correct electrical service, compatible receptacle and adequate ventilation before purchasing.
The included C21-to-P13 cable is an original factory Bitmain cable, not an aftermarket replacement. The electrical meter boxes shown in the photos are not included.
This is specialized equipment. The buyer must have the knowledge required to configure and operate it. I will not be providing setup assistance or ongoing technical support.
