Such mobos can be very useful when you use a dual-system case, such as the Phanteks Evolv X.
The Gigabyte MB10-DS3 comes with SFP+ ports.
The ASRock D1541D4I-2L2T has all the Gigabyte goodies, but has RJ45 10G ports instead, and also provides you with a PCI-E M.2 port.
Finally, the SuperMicro X10SDV-TLN4F tops this with SATA-capable M.2.
All systems utilize the Xeon D-1541 SoC, which provides you with some pretty pleasant performance:
You possibly also want a dual-system PSU – the good news is that Phanteks got you covered with that, too.
At the time of writing, I couldn’t find any 1151 mobos with such features. If you’re aware of any, please let me know in the comments!
