Just put my new 20 Max kit into a hard case I had from a DCK470L. It actually fits everything nicely. The circular saw fits perfect with battery. The reciprocating saw fits only without a battery. The drill fits good with battery, just a little bit off in its cradle, and the light also fits perfectly, with no battery, and charger does as well. There is even a couple spots on the left for a 3.0 and 1.5 battery. I am thinking of cutting or melting into the plastic to fit my impact drill in place of the light but i'll hold off until I order the Brushless model since it might fit a bit different.
I know this is not a big deal but I thought I would share for the hard case lovers.
