CPU: great
Case: looks great, HORIBLE temperatures. DO NOT get it @LeonHienekamp
Motherboard: great
PSU: decent, but not that great.. get something like the Corsair RM850x
HDD: I'd personally NEVER get a HDD ever again, except if I needed LOTS of storage. Get a 2 TB 970 EVO Plus instead
AIO: get a Arctic Cooling Liquid freezer unit which performs better for roughly the same price
OS: get a (legitimate and legal) Windows key for WAY cheaper
RAM: great
GPU: great

Don't pay 100 euro for windows 10, you can get a key for 20 euro off G2A

The cooler that comes with the 3700X is pretty decent. As you mentioned, you're not planning to overclock so it will do just fine.

the msi x570 boards aren't great, they have poor vrm cooling, and they overheat, I'd avoid them.

I have the corsair 275r, not sure about the difference with the 270r but it's a solid case

Stock amd coolers are excellent so don't bother with aftermarket coolers unless you want to overclock
