In that case, I’d probably be thinking of a standard power supply with molex output (they make bricks like this) for a 5.25" fan controller that ties in thermistors on the control side of the equation. I know that’s not the typical, “I just use a raspberry pi and…” answer we’re used to here, so take mine with a grain of salt.
EoL? They’re releasing betas regularly and announced 13.3 for Q2. You mean how they’re sort of winding down with scale taking the bulk of dev cycles? Not much to change with the platform, and security fixes will be backported to CORE. I think SCALE still doesn’t fit my use-case, hut when it does, and jails go away with CORE, I’ll shed a tear and pour one out for my homie.
