i have a passively cooled Quieter 4C [1] with N100 and a 4TB [dram-less] nvme [2] and it draws 4.5W total at idle running EndeavourOS w/ KDE Plasma. at full load (Handbrake 1440p transcode) it draws ~10W.
i left it at stock bios settings and did not put it into higher TDP mode though, since i use it as an htpc and it mostly idles, i'd rather it stay at more comfortable operating temps.
the nvme cost me more than the pc, which for $207 includes 16GB ram, 512GB nvme, and a Win11 Pro license. insane.
