Bill, stick it in your ear ol' chap! 'Tis one of the few times in
polite society you can offer that exhortation in a friendly manner

Get a long shafted screwdriver, stick the handle in your ear and probe
various spots to track down the sound source. 1st wrap the shaft with
electrical tape for safety. It often (not always) works pretty well
in localizing a sound.
You must have a teeny head or a whale of a case to execute your plan
of putting your head inside the case.
If you probe on an inductor or other mobo components, it would be a
good idea to put a small piece of tape on the blade to avoid creating
novel circuits in case the screwdriver slips.
