Thanks for the info.

Do you know how hot they run? Do you use some form of active cooling?

I am using swapspace and pointing it at the RAID, but in normal use,
the box shows about 65% RAM usage and zero swap.

Yes, I am using wired networking.

Last night, I configured wifi as well. I googled for how. For 20.04, I
found a lot of confusing info about cloud-init, which I don't need and
so I disabled and removed it.

So, I used wpa-supplicant and a howto from 16.04. It's in and working
fine and the machine now has *both* wired and wireless connections.

 (I was annoyed by comments in various config files saying "don't edit
this, cloud-init will over-write it." Well, it's on bare metal, it's
manually managed by 1 user, me, and I don't want or need cloud
instances of anything, so I nuked cloud-init.)

It's basically a NAS box. It doesn't run anything not related to being
a NAS. No interactive users ever, except me. However, the things it
runs (ZFS, Samba, Netatalk) need to directly access hardware and are
all inter-connected, so containers would only get in my way.
