Here is a list of all motherboards with the 1151 socket, the Z170 chipset, DDR4 compatibility and at least one PCIe x16 slot, sorted from highest to lowest buyer rating. Price is capped at $140.

I think you should go with Asus Z170 PRO GAMING ATX LGA1151 Motherboard, as it is compatible and there is a combo deal that will save your dollars.

These would be my recommendations.
