A few years ago, I admit it was rare to find someone running Arm hardware more powerful than a Raspberry Pi in a homelab (or more serious) setting, outside of cloud providers running Ampere or custom Arm CPUs. But as Pis and Rockchip boards have become more powerful (and efficient), and Apple's M-series silicon has become more interesting (the M4 mini being an excellent value proposition for a quiet, tiny server), and even Ampere Altra pricing coming down a bit since it's an 'old' server CPU now...
