All this talk has made me glad to pay the premium to stay with x86/amd64 supported boards. I've been buying PC-Engines for years, and run whatever I please on them (but mostly OpenBSD). They are 3x the price of the RPi (more if you want WiFi, bluetooth etc), but for certain applications, are quite a bit more powerful and flexible. This is especially true if you want to remain up to date for years. I have never been left without an upgrade path.
If not for boards, I just bought this https://www.amazon.com/dp/B019Z8T9J0 complete, passive PC for less $150, it has four Ethernet ports and a HDMI and a Broadwell (not Atom!) CPU. It's rather incredible how cheap PCs gotten.
