One final thought for now. I've been quite keen on the FG Elektronic PSUs, but its occured to me that the "old" generic designs do have an advantage. FG supplies have both the transformers and the heatsinks screwed and soldered directly onto the PCB.

The old supplies use the heatsink as the chassis instead. The transformers and the PCB are separately bolted to the heatsinks instead. Its useful to have the PSU chassis bolted directly to the equipment case, for the benefit of heat-sinking. I'd stil like the option to decouple the transformer from the chassis though. This provides the ideal mechanical configuration, where the transformer is decoupled from the case, but the heatsink is firmly coupled.

You can do that with the legacy Condor & Power One supplies, but not with the FG supplies. If you wondered how important decoupling is, take a look at the cooling fan in any recent piece of electronic equipment - that's very likely to be de-coupled with compliant rubber bushes. Just a thought.
