Looks good, like the plan
As mentioned earlier, this is basically spending money for the sake of spending money. Not only will you see no significant benefit in the real world, but you've also closed your opportunity to upgrade to 64GB; if you wanted to do that, you'd have to buy a completely new set, rather than just being able to buy another set of 2 matched DIMMs off of eBay 5 years down the line
Looks good to me. Keep in mind that the only thing the software controls is the lighting of the fans (and maybe the pump speed? That'd be more up to the motherboard, though). So if you wanted to just use the controller box to set it once, without syncing with the rest of the lighting necessarily, that'd be fine. Otherwise, if you're certain you'll be using an Asus motherboard, get a cooler with fans that say they support "Aura Sync"
I guess I'm a little confused as to why you're not going with the PSU the parametric filter recommended in my revision; again, there's spending to get a better value, and then there's just plain wasteful spending
Same applies here; the 970 line just isn't a big enough step up from the 960 line to justify the enormous price leap
I gotta say, I'm a bit amused by the fact that you say you didn't like the case I picked out, then picked the exact same one that I did, but with RGB fans and a white interior
