As far as ram is concerned, I'm opting for the corsair dominator titanium 6000 with 4 x 32 gb in case 30. Why corsair and not g skil? because I don't want to mix several RGB management apps, even if signalRGB can take care of it. For the m2 gen 5, a corsair mp700 2 tb and for gen 4 a 990 pro 1 tb (dedicated to installing games).
