Best thing you built or fixed this month

Reading this from {place}, my seed backup plan finally moved from paper to steel this month. Sleep improved. Am I missing something obvious?

I moved everything to a Pi node and the difference was bigger than any chip tweak. Would you do it differently?

The real cost is never the rig, it's the 923W nobody budgets for. Anyone tried the opposite?

Underrated topic. a 3334W night-tariff window is the closest thing to free money in home mining. Numbers welcome.
