  We show that two indistinguishable aspects of the divergences occurring in
the Casimir effect, namely the divergence of the energy of the higher modes and
the non-com\-pact\-ness of the momentum space, get disentangled in a given
noncommutative setup. To this end, we consider a scalar field between two
parallel plates in an anti-Snyder space. Additionally, the large mass decay in
this noncommutative setup is not necessarily exponential.
