I'd place a vote for the Antec SX1030, or SX830. They are both nice cases, with very good stock cooling (4*80mm, and the brackets are designed such that there is virtually no vibration from the fans, and hence little noise).
And yes, the FOP32 is loud compared to a Taisol HSF, because the FOP32 uses a YSTech 27cfm fan, which is a relatively high RPM fan. It's nowhere near as loud as a Delta fan, but it's still loud. The Taisol fans are great coolers for the noise they produce, a CGK is around equal to a FOP32 for less noise.
