No danger at all. The metal case is a shield, the case of your harddrive
is a 2nd one - and the distance in between even more so.
It would need a *much* stronger magnetic field like that of a NMR scanner
to really erase data.
Of course, pinning your atm card (with the magnetic stripe) or one of
these outdated floppy disks with a refrigerator magnet, would not be such
a good idea - no shield in between and a much lower distance.
