Very pleased with this case. Excellent build quality. Nice understated looks. Well thought-out layout, making cable-management a cinch. Plenty of room to reach all components, and easily accommodates even the largest coolers.
As to how quiet it is - I guess that will depend on the components you choose. Don't expect it to magically eliminate all noise. There will always be a trade-off between airflow and noise-reduction, and this case has pretty decent airflow, so the noise-reduction is limited, but still worthwhile.
In my build, I have a Core i9-9900K cooled by a Noctua NH-D15S and for good measure, I bought an extra Pure Wings 2 140mm fan for the front (my only quibble is that I wish they had included that by default). I used a Corsair RM650X PSU, whose fan turns off unless the load is above a certain threshold. With that configuration, it is completely silent when idle.
Under maximum load, the fans are definitely audible, but not much more than a whisper. The CPU reached 70C (all cores at 4.7GHz), consuming about 150W. Not too shabby.
