These ones have caught my eye, but if you have a better suggestion, tell me.

I know that the OCZ, XFX, and Rosewill Hive PSUs are good.  Not sure about their CapStone series.

I would go for the XFX PSU, because of personal experience with one.  They're on a Seasonic design, and are both quiet and cool.
