Welcome to the ROG forums, Fidelis.
I see no faults in your build. I do have a few personal recommendations if you'd like to hear it. LOL
If you're getting the Dominator Platinums for their looks, then I understand.
😛 But on a price/performance level, G.Skill is hard to beat especially their Ripjaws Z Series. You can get the same performance, if not better, for $30-$50 bucks less.
No idea if Seasonic still makes some of the Antec PSUs out there. In my books, Seasonic is the guy to go to when you're looking for a PSU to power your high end rig. True, sometimes a Seasonic unit costs a little bit more than a competitor's unit, but you're not just paying for a rebranded unit. You're paying for the real deal.
😉I don't think you'd need RAID 0 for a solely gaming machine. Instead of RAIDing 3 256GB Samsung EVOs, I'd just get the 1TB variant. Besides, having a RAID array adds a few seconds to your boot time. Something I don't like personally.
