We recently installed one of these basically as digital signage, but I
think it should work fine for your needs too.  We've had no issues with it
at all. (we installed ubuntu)

It's the ECS Liva mini-pc

Hopefully not too far off topic for this list.

Am looking for options to deploy DNS caching resolvers at remote
locations

We're BIND-based and leaning to stick that way, but open to other
options if they present themselves.

I've found that "unbound" is lighter on the machine, but it does depends
what you require feature-wise and/or operationally, of course.

Am considering the Soekris net6501-50.  I can dump a Linux image on
there with our DNS config, indudstrial grade design, and OK
performance.  If the thing fails, clients will hopefully not notice due
to anycast which will just hit another DNS server somewhere else on the
network albeit with additional latency.  We ship out a replacement
device rather than mucking with trying to repair.

If you're looking at Soekris, you might also find the PCEngines products
interesting.

The "APU" series appears similar at a glance - and they do offer a case
(not rackmount, sadly - although 3rd parties might) to suit.

At the lower end, the "ALIX" boards are available in a standard 100mm x
160mm "eurocard" format which makes them very easy to rack up..

Whichever way you do it, a small low-power box running entirely from flash
or ssd is likely to be a good "fit and forget" (security updates aside!)
solution.

If you want to run from a cheap flash card, and are a linux shop,
http://linux.voyage.hk/ is a debian-derived system targetting the
PCEngines boards which runs with a read-only filesystem.
