you need 4 things for a silent system: low noise case fans, low noise CPU fans, low noise GPU fans, and a quality PSU (with low noise fan).
my antec 300 has 6 fans on/in it, but because they're all quality low RPM fans my system is dead silent. even under load its noise is unnoticable from 2 feet away while still maintaining near ambient temps inside.
What are the quality fans you used? That sounds like an easy way to go.
i built my antec 300 system a while ago so you'll have better/different fan options now, but the fans i've got in it are:
- included tri-cool on top, set to low
- scythe somethingrather on read and side exhausts (if i were building it now i'd look at noctua)
- a zalman cnps9900 on the cpu (most any tower cooler will be quiet)
- a silencer mk II PSU (most 80plus PSU's are also quiet)
- an aftermarket accelero twin turbo II GPU cooler
- did not put any fans on the front grill (relied on negative pressure for airflow)
