I've bought recently the 12600H version barebone and I'm super happy with it, BUT:
1) I've bought the Crucial 1x 16G 1,1v 5600 DDR5, but the bios is showing 4800 and there is no way to do something about it.
2) I've installed OPNSense and I'm having big issues with the X710 ports and IGMP and Multicast traffic (IPTV), and that doesn't make me happy. I have use 1 port from X710 for the WAN and 1 port from the i226v for the LAN, but I have more latency, than using both ports x710.
apart from that, very nice build and very good price!
