I got mostly the same setup as you and I ordered the case in the same opening week as you. (arrives in the first week of January)

I have watched all the videos and followed a lot of posts and so far I do not see any issue with your build.

Out of curiosity, any reason why you ordered corsair H100i over H100i RGB Pro XT? It is $110 right now:

Also, the chromax versions are cheaper than the regular ones. Amazon is not carrying the regular ones anyway.

SF-750 is hard to get. Just got mine from Amazon a week ago and it was by luck.
