That's great except where you ignored my observation of name-brand caps that have failed. Again, computers are cap hell. A modern CPU has to dissipate over 60W. Making a cap live next to the heat equivalent of a light bulb is going to test it to its extreme. Sometimes they fail as a result. Some fail sooner than others, and yes, some sooner than they should. All of them will fail within the useful live of the mobo for the simple reason that their life is measured in thousands of hours (and according to the ambient temp). Of course, the mobos are generally obsolete by the time the better brands (and mobo designs) would normally fail, but still, the caps will usually be the first point of failure. Go to that "bad cap" forum or whatever that was, and you'll see failure reports of every brand.
None of this has anything to do with an audio device where total power in the circuit is measured in milliwatts and which has a long reputation of stageworthiness . . . so, please stop scaring the poor newb into thinking he's bought a POS.
