I have a hp T620 in use for that purpose and it's fine.

I shoved in a cheap M.2 and connected a spare drive via USB 3.0 and now it does backups and archival duty for less than a @Raspberry_Pi #Pi4B4GB or #Pi400 would've cost me #MSRP!

It's also fanless and barely sips 10W when under full blast as 80% of the case is just a giant-ass heatsink that is bigger than a flattened-out Noctua NH-D15!
