In general a great build, but...
1) 1000W PSU is way overkill for those parts. I err on the side of going high myself and see no need for going above 750W.
Gaming is probably roughly 400W. The reason for 750W to me is to keep the PSU fan speed low since they often ramp up around 50% load though there's some models that turn off the fan at 50% or even lower.
THIS should be a great PSU that has a great fan curve for minimal noise (use the "Fanless Mode" which then disables the fan below 30% load so in light usage it should be fanless and in gaming the fan will turn on):

2) CPU cooler:
I'm not a fan of liquid cooling. You'll get a small boost to the CPU overclock by getting a better cooler but the default is pretty good. Normally I like air coolers like the Noctua... the best one I'd recommend for that build would be the Be Quiet Dark Rock 4.
I think this cooler looks good in a black/white build, should be fairly quiet but also avoid the potential pump noise or fan speed issues many liquid coolers can have.

Use the motherboard fan speed software to optimize the fan curve to be as quiet as possible while keeping within temp.
3) Why not go with an M.2 2280 version of that SSD to eliminate the cables?
