It’s an Asus XG-C100C https://www.asus.com/networking-iot-servers/wired-networking/all-series/xg-c100c/
It works very well, but doesn’t support WOL. None of the cards on the market at the time I bought did, but I think there is one now.
My current editing system is many years old (x99 8 core 6900K), so long overdue for a refresh.
Ah ok, I didnt know. I have the same one in my main PC. But I have Intel X540-T2 in my other machines. Not sure if they support WOL, the NIC are cheap off ebay.
