We present a comparative study of the anisometric and anisotropic magnetic colloids at low temperatures. As examples we choose the ellipsoidal and cubic magnetic colloids to illustrate the influence of the Shape (particle anisometry) On the ground state structures. To scrutinise the influence of the internal particle anisotropy we address particles with dipoles shifted out from the centre of mass. Of the latter, we distinguish between two types: the first type has a dipole moment pointing radially outwards; the other has a dipole pointing perpendicular to the radius along which it is shifted.
