And the Snap-on chest the OP posted has 3 deep drawers and 4 shallow drawers all in one housing, and no top tray. There is not a way to fit 3 deep and 4 shallow drawers in the Pelican no matter how you reconfigure it.
They don't.
Here's some links
The OP has this:

There are other versions with a different drawer layout in the same case.
The other Snap-on one is this:

There are other versions with a different drawer layout in the same case.
There are also different color options for those cases.
This is the Pelican case:
0450 Protector Mobile Tool Chest, a portable toolbox with tool organization. Available with 4 shallow / 2 deep drawers, 6 shallow / 1 deep drawers. Interior: 20.6" x 11" x 12.7".

There are 2 drawer options.
If you look at the cases, you will see that the drawers aren't the same, the handles aren't the same, the dimensions aren't the same, and even the wheels are on different sides. Those are not the same case.
