Like the previous post, Asus PRIME Z270-A motherboard is one of the right choices I guess. This is an alternative that is widely used by miners because it is easy and the price is quite affordable.
My uncale also used same montherboard like you mentioned. I've learned from him that its very useful and untill now its working smoothly without any issues.
As long as that will be matched with your budget and that will not bring yourself in the lose and that's will be useful. to build a mining rig is not just about to use the latest mobo that can be putted a lot of GPU too. there was a lot of reasons need to be considered.
