Nucs also tend to win on performance, software compatibility/upkeep (yay commodity x86), price per performance, and often price outright (pis aren't really $35 if you get a newer/better model and once you buy storage/power/case). AFAICT pis only consistently win on power consumption, and that only just (x86 can get well under 10W, you just have to get the right model)

Thin clients are also an option.

Similar power consumption but power and case/cooling/storage is included.

Depending on what you choose you get eMMC or SATA or M.2 SATA or M.2 NVMe for storage.
