Mine had a noisy fan on the NForce3 Ultra northbridge, which I replaced with a passive cooler, northbridge runs a little warm now so may have to put a quiet fan on the side of the case to improve air throughput. Main fan is almost silent so that the "quiet" psu fan is actually louder. Disk is a Seagate S-ATA which is actually pretty quiet. I'll experiment with different filesystems in a bit to see if that has any bearing on sound. Reiser4 seems smoother and quieter in one of my other boxes. Good luck with the sound. I'll post if I have any luck with mine.
You have an Athlon64 in that, right? Here's a suggestion: If you aren't already doing it, make sure that you run powernowd (or something similar). The PowerNow technology in the new AMD chips is great. My desktop machine has an Athlon64 in it and with powernowd running, most of the time the CPU temperature is right around 30C with the CPU fan turned *OFF*. Powernowd keeps it downclocked to 1GHz except when more power is actually needed, and I'm using fancontrol to automatically adjust the fan speed based on CPU temperature. Fancontrol is configured to turn the fan on at 35C (at low rpms, higher temps gradually speed up the fan; it goes to full speed at 50C), so my CPU fan is off nearly all of the time.
In your case the Shuttle ICE fan is pretty quiet anyway, but it can't hurt to keep that processor as cool as possible. If nothing else to keep the ambient temperature inside the case as low as possible to help keep your northbridge cool.
I don't regret going with the slower CPU for this media PC -- it really won't need even the horsepower that it's got -- but I do wish that the Sempron had PowerNow.
