If a loud buzz were directly caused by some electrical fault, I'd
be sure that it would become a catastrophic failure (bang, smoke,
blown fuse, bad smell) within a minute.
It sounds more likely to be a panel buzz, i.e. two of the sheets
of metal have started to bang together, probably excited by the
(small) vibration from the hard drive.
If you haven't interfered with it, the power supply is entirely
safe to touch with fingers from the outside. It's impossible to
accidentally touch any live connections. You can safely grope
the thing and see if your fingers damp the noise by pressing
somewhere.
