I've just done 2 seconds research on the fanless PSUs. As far as I can tell, the heatsink on the outside of the case, or the case itself for some models, is not thermally connected to the hot-bits at all.
The model I looked at in a review with internal shots (sorry, lost link, but google and you will find) had heatsinks on each end of the PSU, outside the PSU case. These heatsinks were connected by heatpipes to heatsinks inside the PSU. However, these heat sinks only get heated by the air that is heated by normal heatsinks on the hot bits.

I suppose, in the end, the risk of manufacturing faults causing PSU casings or heatsinks to be live, is just too great to bare? Can anyone confirm my guesses based on review photos?

Now, I suppose you should consider that the PSU has higher spec components designed to live at higher temperatures.

In which case, perhaps an easy way to WC a PSU is to take a fanless PSU, strip it out of its case, and then mount it in a custom case that includes a small radiator in it?

Man, it just doesn't make sense to me though...
