For my fileserver I am using a Gigabyte X470 Aorus Gaming board
with "qualified" ECC RAM (dmidecode confirms this) but I am not
sure if FreeBSD has ECC support for such boards. At least I don't
know how to tell!

What I really want is a laptop with ECC to use as the fileserver
to avoid having to deal with UPS that lasts a few minutes, cabling
and suboptimal support from NUT. SSDs are fast enough for me.
Laptop batteries last long and are easy to replace and easy to
test when to shutdown the laptop. And less heat and space!
