I have a broken SGI Indigo I'd like to fix, but I have no idea where to start.
The most obvious problem is that shortly after power on - two seconds, maybe
three - a noise starts coming from the internal speaker. The sound becomes
louder and louder with every second. No startup chime, no output on serial
console.
My initial thought was a broken power supply, but a PSU repair guy I've found
claims that power supply is ok and voltages are correct and clean. He also
says that he tried to bend the "mainboard" - probably the CPU board - slightly
and this sometimes leads to the startup chime.
Any suggestions are welcome. Thanks :-)

Yes. No solution, unfortunately.
One more data point: when I first got the machine, it worked ok for a few
hours. Then, at some point, it started to emit this awful noise.

I call trick question.
You wouldn't say either one, because you'd be too dead to talk.
The question lurking underneath is interesting, though, I agree. I'm
not sure which I would think more appropriate in general; personally, I
tend to locate my self a few inches behind midway between my eyes, so
I'd probably go with "me and my body".

Sounds like a marginal component fails once it warms up and now it's
failing sooner.
In a computer system, it seems the most commonly failing part is a
capacitor. Since there is noise coming from the speaker, I'd put an
oscilloscope on the speaker terminals and see if you can spot an
increasing noise level on the terminals.

Have you tried the reset button after power up? My O2 sometimes doesn't
fire up first time until I've reset.
