All computers are NAS if you stick S on them and A them to an N, the Raspberry pi is no different, but it's got a great advantage in that it's small and relatively power efficient. I turned a Dell Optiplex USFF into a NAS (https://willj.net/posts/fitting-two-hard-drives-and-an-ssd-in-a-dell-optiplex-7010-usff/ https://willj.net/posts/fitting-two-hard-drives-and-an-ssd-i...) but in the same space I could easily fit 4+1 disks instead of the 2+1 if I was using a far smaller motherboard. As for being underpowered, again it depends what you are doing with them. For my NAS (basically long-term storage of stuff I don't access much and tiemmachine backups) there would be plenty of CPU, the biggest problem would be memory. *edit* Just to be clear, the Pi has some massive drawbacks as a NAS at present because of it's significant lack of disk IO, but there's nothing inherent in it's form factor that makes it a bad NAS. If I could have plugged 2+ HDs into one in a performant way I'd likely have done that rather than the Dell Optiplex shenanigans.
