This is a very poor value build but since you insist on not switching to AMD (where you can save about $100 and get a better performing processor and nicer motherboard) here is my advice.
GPU: The GPU you have selected is overpriced at $299. You should go find an RTX 2060 for the same price or maybe even less.
Cooler: There is no purpose in getting a liquid cooler for a non overclockable CPU.
PSU: Maybe you can try to upgrade that PSU to 650W to be safe IMO
other than that your build looks fine.
Id assume you're on a tighter budget. Ryzen 5 3600 + MSI B450 Tomahawk is way better value for money, it also includes a good enough cooler.
I'd suggest higher storage, ssd and perhaps slightly better psu
Regarding cpu(as others are suggesting)... yes, well amd does have somewhat cheaper and as far as I know(heard) better cpus but you need to figure out how important it is in practice, for example I have 5yo build and i5 4440 in it.. got 0 problems... just make sure when you make a build that it's going to last for couple of years
change intel to amd 3000 series
as everyone said, 5 3600 in this price range is just way too good not to buy and i think even if you get x570 mobo (more expensive but no need for bios update) theyd add up to similar price
Too much RAM means nothing downgrade to 12 and save money
Also how much does 1 GB SSD cost!
Get AMD and ditch that trash GPU
