Well no, not on the top in the photo, that's line filter, more or less a 5 pole line filter, plus some ferrite bead and extra ceramic caps on the mains entry, by the looks of it. Definitely a PFC choke on the left though, the black core probably being Kool-Mu. Not sure why there are so many devices on the heatsink, I'd expect four (1 MOSFET and 1 diode for PFC; 2 MOSFET for output, most likely 2-switch forward).
Most likely failure I think would be something missing from ground. Measure the caps. Check the secondary side grounding, it should be shorted to the case, possibly in multiple locations.
Could still be some kind of electrical failure, other than failed filter components; a transistor accidentally shorted to a heatsink, or insulation failure in the transformer maybe, could do that I suppose (if unlikely without also shitting the bed completely).
