What about the Gigabyte h110-d3a ?
A lot cheaper than the Asrock and it looks like it was made for mining aswell.
Don't see many miners using it though.
Oh I see Gigabyte has also made a mining motherboard like the Asrock and Biostar and I must say the Gigabyte brand is perfect (having my own Z97 Gaming 3 running 5 Gpu-s in a gen 4 motherboard without problems) and is better than Asrock and Biostar.
One thing I disagree is the H110 chipset, is the lowest chipset of gen6/7 motherboards but if Gigabyte says it is perfect for mining then it is. For me is my top brand together with MSI.
