Something small and 2 or 4 GB RAM. Raspberry pi's compute power is good enough for me, I'm not doing anything too intensive.
Is raspberry pi 4 still the best answer?
I am a tinkerer and don't mind tinkering. I typically use Gentoo Linux as main OS. I also don't mind ARM or other architectures. I've been eyeing the RockPro64 as well.
yeah, it exposes PCIe, i forgot about that. but still a single lane and requiring an additional adapter card and ribbon cable that complicates packaging a bit and adds cost. I dunno, I'm sour on Pi these days since they've spent years screwing over consumers in favor of business customers. I've chosen not to buy their stuff despite the better software support.
