I finally got public pool configured on my Pi 5 too. You can customise the Pironman case and set the fan speed etc, not very noisy at all.
What I have found though is that public pool gives me more rejected shares than ckpool...
I'm quite pleased with the Pironman Max case its well thought out and pretty easy to build.
I've pointed 3 workers (approx 7TH/s) at my CKPOOL set-up, other than 2 shares being rejected at start-up its been running flawlessly.
In fact my BitAxe Gamma hit its all time best share yesterday morning which was a pleasant surprise.
I'm working on getting a local stats web page up and running on it too, but thats going to take some time as real world issues have to come first.
In terms of usage stats, its been
consistenlyconsistently running with <2% CPU usage and around 1.7GBytes memory usage.
So, quite capable.
