A mobo battery would only light a blue LED for about 10 hours.
Low voltage LED with the mobo battery & mobo caps feeding it can run days. Unless you have better explanation ie. the board being possessed.
Your standard blue LED has about 3-3.5V drop across it and draws around 20mA. The mobo battery is 3V and 220mAh. That's a bit under 10 hours of light before the voltage in the battery drops under what's required for the LED to light up. That'd also be quite noticable on the operation of the computer, as it'd forget the CMOS settings every boot. Capacitors in a normal computer are quite irrelevant. If you were to dump all the power in the 12V rail caps into the LED to discharge them, it'd still just light up for a minute or two.
I am still waiting for the punch line: where do you think its getting the power? I am just asking worthy alternative to the mobo battery scenario.

I have no idea. All I know is where it isn't getting its power from.

One possibility could be a super-cap, but that's quite unlikely, as those cost several dollars each.
The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP
