You are right about ice, but metals (which are comprised of neutral atoms which lack an intrinsic dipole moment like that of H2O, and nearly always have crystalline structure) are not held together by Van der Waals or similar forces - one needs to invoke quantum mechanics to get even a qualitative picture of why they stick together. Consider for instance Sodium. If there were no force other than Van der Waals holding the atoms together in the crystal, there is no explanation for the fact that Argon, a significantly heavier atom, has much lower melting and boiling points.
