Noise comes primarily from small fans running at high rpm.
Two components require cooling, the cpu and the graphics card.
Start with the graphics card which is a fixed choice for you.
To cool the card, it will come with probably three 90mm fans.
Such small fans need to spin up to relatively high(and noisy) rpm to cool the card.
Not much you can do about that except to insure that your graphics card coolers receive a good stream of fresh cooling air.
The front air intake for the case becomes a prime design requirement.
On the cpu side, you will want adequate cooling.
You may be tempted with a 240 aio cooler, but I would not see that as a good thing in a well ventilated case.
A good dual tower air cooler like the drp4 pro or noctua NH-D15s will cool equally well.
The large 140mm fans can run at lower rpm and cool equally well.
On the case, look for one with larger front intakes such as 140 or 200mm which will turn slower and quieter.
I like the cm h500 mesh.

It comes with two front 200mm intake fans and has plenty of room for a good tower type air cooler.
Another source of noise is possibly a mechanical HDD.
Include only ssd storage if you can.
If you need bulk HDD storage, pick one of the quieter and slower HDD devices.
Lastly, pick a quality gold rated PSU of adequate capability.
I have no problem overprovisioning a PSU a bit. Say by 20%.
Likely 750/850w.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
A quality psu like the seasonic focus units will have a 7-10 year warranty.
They warn you to not be concerned if the cooling fan does not run.
The fan will only spin under the heaviest of loads.
