Do you mean the board inside the case?
If so, the whine you refer to is probably caused by mechanical movement
in the inductors due to change in the magnetic field.
Try to power up the PC and see if you can locate which one(s) the wine
comes from by applying a small amount of pressure to the coils/ferrite
rings. You should then be able to apply a few drops of e.g. hot glue
between the coil windings to make it completely silent.
Good luck! :-)
