Rig-Building Question. Good mobo for 4xVega56 rig?

[keksov]

I'm going to build a 4xVega56 rig, please help me decide on a motherboard for the setup. Share your specs if you have build one already.
What would you say about ASRock B150M Pro4S http://www.asrock.com/mb/Intel/B150M%20Pro4S/ ?
Do I need 8G of RAM per each Vega card (32G total), or 16G will be enough for all 4 cards?

UPDATE: list of some possible mobos here https://www.reddit.com/r/MoneroMining/comments/77cq6j/good_mobo_for_4xvega56_rig/

MOB: MSI Z270A Pro (USD 99)
CPU: Intel G4400 (USD 55)
RAM: 4GB DDR4 (USD 40)
SSD: 120GB (USD 60)
PSU: Dual Corsair RM1000x (USD 175 each)

Why Dual PSU? Vega is power hungry GPU, thus requiring a lot of power. One Vega can take up to 250 to 300W. Don't go cheap on PSU!
