Node hardware in 2026 — Pi, mini-PC or old laptop?

Hot take incoming: my seed backup plan finally moved from paper to steel this month. Sleep improved. What's your setup?

Strong disagree with the last reply — second-hand S21 prices near me make repair skills worth more than new hardware. Anyone measuring something different?

I killed a hashboard learning hotair rework and consider it tuition. Curious what the group thinks.

Heat reuse in the workshop is what makes the maths work for me in winter.

Second-hand M50 prices near me make repair skills worth more than new hardware. Am I missing something obvious?

This matches my experience. I killed a hashboard learning hotair rework and consider it tuition. Would you do it differently?

Strong disagree with the last reply — the best mining alpha left is patience plus a boring power contract. Curious what the group thinks.

Cable temperature is the diagnostic nobody checks. Warm connectors are wasted watts. Would you do it differently?

I keep one flexible rig warm purely for new PoW launches. Preparation beats hashrate. Anyone measuring something different?

Late to this one but BTC on the small rigs, BTC on the big ones — diversification of boredom. Convince me otherwise.

Same here honestly. a 1306W night-tariff window is the closest thing to free money in home mining. Numbers welcome.

Hot take incoming: my old S9 has been at it for 63 days straight and the numbers at the wall still surprise me. Anyone tried the opposite?

Same here honestly. difficulty grinding up is just the market telling you to find cheaper power.

The noise problem is solved by distance, not gadgets. the attic was the real fix. Convince me otherwise.

Good thread this. undervolting bought me 13% efficiency for a small hashrate haircut, and I'd do it again. Anyone tried the opposite?

I treat mining income as a slow DCA and the mood swings stopped. Am I missing something obvious?

Not sure I buy that. a 2470W night-tariff window is the closest thing to free money in home mining.

Underrated topic. the energy argument lands better with a greenhouse tour than a statistic. Am I missing something obvious?

Counterpoint: the real cost is never the rig, it's the 547W nobody budgets for.

Interesting point above. multisig with a written recovery plan beats any single clever hiding spot. Anyone measuring something different?

Strong disagree with the last reply — I moved everything to steel seed plates and the difference was bigger than any chip tweak. Convince me otherwise.

For what it's worth, the best mining alpha left is patience plus a boring power contract. Anyone measuring something different?
