Removing the lower case...

There are no more rubber feet to tear off!

Eight Phillips #00 screws hold the lower case in place, two less than the 13" Pro.

The lower case is surprisingly heavy, weighing in at 266 grams. The lower case is actually a sheet of aluminum with rubberized coating injection-molded onto one side.

In contrast, the lower case on the 13" Pro weighs only 142 grams, so the rubber coating nearly doubles the part's weight.
