I can't imagine a
many-particle system "with only a small number of energy levels".
Imagine a gas of non-interacting Bose particles in a box. The single
particle spectrum is discrete and is determined by the boundary conditions
at the ends of the box. Bose-Einstein condensation occurs when the box is
cooled sufficiently for many of the particles to end up in the ground state
of the system.
That, in fact, is the definition of "Bose-Einstein
condensation".
