Hi Tony,

As you probably know, various low TDP Intel CPUs support the
AES-NI instructions, and newer OpenSSL has the ability to offload
that to the CPU.
E.g., my 3.5 year old Macbook Air has a 15W i7-4650U CPU @ 1.70GHz,
and it has the AES CPU instructions.

How about an Intel NUC or one of an equivalent/cheaper unit
from Gigabyte (etc), with a 15W or 35W CPU?
Or is that outside your power/cost budget?
