Inside a dinky little 5V 600mA PSU.

I added this item to an order because it appeared to be a 5V PSU in the standard housing used for many 3W LED drivers. I was wondering if it was going to be based on similar circuitry fudged for a 5V supply.
It turns out to be a full-on switchmode with opto-isolator feedback to a genuine SMPSU control chip. A THX208.
I would not classify this PSU as being suitable for powering stuff that was being handles, but for a 5V supply within equipment it seems acceptable. The clearance on the PCB is around 3mm.
The ebay listing I bought this item from was:-
