Before I stick it on eBay - does anyone here want to buy my classic Bitmain Antminer R4 home heater ASIC (plus 1200w APW3++ psu)?
These are extremely rare. Basically an S9 in a very different form factor, cooled by a quiet impeller rather than server fans - like an air con unit.
If you do, send me offers by DM. You'll have to pay me first, and trust me to deliver the unit. If that worries you various UK bitcoiners can vouch for me.
Only one of the two hash cards is fully functional, the other mostly doesnt come online. Therefore it's a 400w 4TH/s machine.
