-Looking more closely, the two middle-side filter caps; C41 and C42, have been replaced with the original values (5600uF, 10v). //But//, the current recommended wisdom is to uprate these to 6800uF parts, which have been known to cut out PSU noises for several owners.... and this is exactly what I did:

 That's audio taken with the covers off, and the recording made approx 8 inches from the rear of the power supply. Boosted by approx +15dB. There's a tiny bit of white noise from the turbulence from the fan, but it's otherwise silent. I am //very// happy. :-D
+**[Update 29/03/2021]** - With the case covers back on, and the fan now exhausting through the rear grill, there //is// a bit of fan noise that wasn't apparent with the case off, but it's very low level and nothing horrendous at all. It's likely that the grill on the case is causing turbulence from the fan exhaust, so there's not much I can do about that, short of cutting out the grill - which I am //not// going to do.
