There were two sheet metal shelves permanently attached in the cabinet, but I had bigger things in mind. I used some wood to shim out drawer slides so that drawers would clear the lip around the door.

The drawers themselves are simple plywood boxes with a profile routed on the front for easy opening. You can also see the storage on the inside of the door I made for a couple of handsaws, a long ruler and some winding sticks. The latches for the saws are attached to the door using PSA (double-sided tape), and the ruler and winding sticks are on hooks that are magnetic.

Rather than just throwing tools in the drawers haphazardly, I wanted to have a home for each tool, which meant fitted liners. I divided up tools by use (and size), and layed them out on pieces of paper sized to each drawer.

I traced the tools, scanned in the drawings, and then used Inkscape to digitize the layouts.

I'm lucky enough to have friends with a laser cutter, and cut the tool caddies from some 1/4" acrylic. (There are some online options for those without direct access to a laser cutter.)
Here are the layout tools:

Drills and some shaping tools:

The third drawer has an extra caddy for chisels:

Definitely convenient to be able to move these around and have easy access to the chisels:

More shaping tools, smaller saws, and sharpening accessories here:

The fourth (and largest) drawer is a bit of a catch-all for tools that don't fit elsewhere:

I've really enjoyed having the rolling storage — it's nice to be able to move tools to where I'm working, be it the table saw, drill press, or the workbench.
