Hi sorry for the double post, Ameri-rack got back to me. According to the person at sales the z170m-itx/ac supports bifurcation if you update the bios.
Edit: He says this holds true for the gaming variant as well. Does Bios 1.50 have any bifurcation settings available?
Hello, long time lurker here. I recently got into contact with Ameri-rack and they do in fact sell a bifurcation variant of the z97e-itx under the designation z97e-itx/acn. Sales say it's $155 per unit, but you need to contact them in order to get a link to purchase it.
Have asked about a z170...
