[ale] NUC vs. RPi mail server

[agcarver+ale at acarver.net (Alex Carver)]

For a personal mail server that doesn't handle much traffic (less than
100 messages per day), which would you consider/choose: a NUC or an RPi?
 Mostly headless operation (except for getting console to do maintenance
when remote won't work) with a very basic install (no GUI).
