That’d be my go to option probably if I wanted to move off my Pi's. Locally something like a HP EliteDesk 800 G2 (ex business) on deal sites are not much more than a Raspberry Pi, especially the past 24 months where supply of Pis has been hit hard. Those small form factor PC’s probably come with an SSD also which I’d take over an SD card for ruggedness any day, and if you had to buy one and a caddy because you don’t have any spare, the Pi is possibly costing more than the Intel PC at that point. More ports (and more convenient display output if you need it) etc too.

As you say, power consumptions the one thing to keep an eye out for I’d say, but those systems are relatively efficient.
