In my previous post about how financially viable is a Bitcoin ASIC miner as a space heater I talked about buying the s9 miner bundle from [Crypto Cloaks](https://www.cryptocloaks.com]. Their setup is good if you aren’t ready to diy but lets take a look at the financials behind diy.
Parts
- Bitmain/Antminer S9: I’ve seen these on ebay for around $120.
- 2 140mm Noctua fans: $60
- 1 60mm Noctua fan: $15
- (optional) 3d print the Crypto Cloaks case at a local library or hackerspace.
- Total: $195
Updated Comparison
So we are looking at a total of $195 instead of $360. That would bring our ROI down to about 5 months, not bad.
There are a few things that you have to keep in mind:
- This assumes you are comfortable soldering the correct connector on the 60mm fan, if not you can buy an adapter.
- This assumes you can plug the miner into ethernet, otherwise you will have to buy a wifi adapter for it.
Further Thoughts:
- By running a Bitcoin mining node you are helping to secure the Bitcoin network.
- Running a Bitcoin mining node is a good way to get KYC sats.
- What is the opportunity costs of putting ~ $165 into a ASIC miner rather than inviting it?
- As ASIC miners decrease in cost, and Bitcoin increases in cost it will make even more financial sense to use an ASIC miner instead of a space heater.
