I've recently had the opportunity to get my hands on some old mining hardware.

  • 3 Antminer S9 (14 TH/s)
  • 1 Antminer S9i (13.5 H/s)
  • 5 Bitmain APW3++ Power Supplies
I managed to find these somewhat locally and all I gave him in return was a bag of peanut m&m's (good taste, fair enough).
I'm new to mining and kind of Bitcoin in general. I've just got a couple of solo miners so far. I know these are ancient at this point compared to current standards, but I also found a lot of people still have love for these guys for the reliability, and still bring them out especially in the winter to use as heaters. Perfect. Planning for now to turn one or two of them into space heaters and run them in the garage. Noctua fans, 110V, WIFI. Winter is in full swing and it's pretty cold in there while I'm working on my cars. Still need to order parts but I'm basing a lot of this off a guide from CryptoCloaks from a couple years back. Big thanks to Rick for being super helpful as always. It makes this so easy for me. I wasn't really looking for four S9's, but free is free. I'm just excited to get my hands on some old hardware and start tinkering. After two for the garage, maybe I'll start looking into an S19 for the basement. I already have the power supplies.

If you have been there done that with an S9 throw me any tips you got.
