I don't agree with your choice of Ryzen about "good value for money". At least, for a server.
It's one of the most interesting desktop processors put out from AMD during last 12 years, one that really challenge Intel lineup. So it will be really a crack during next 3 years... BUT.
Intel optimized consumptions during last 3 generations of desktop CPU (Broadwell, Skylake, Kaby Lake) with a little bump of multimedia performance into embedded GPU. And now boosts performance adding a couple of "free cores" when AMD try to make the move with Ryzen and Threadripper.
Therefore, putting 8xxx Intel into market, 7xxx, 6xxx and 5xxx remaining stocks could be a bargain for cost-effective (and energy effective) CPU buyout.
Obviously, this is only an opinion related to nethserver use. A simple installation for firewall uses has a GX-412TC CPU onboard, which performes quite well neverthess is a platform released into 2014
