I have been buying these parts storage boxes from Harbor Freight Tools for the past 3 years or so. I had not thought of building a cabinet for them until I saw a video of Adam Savage from Myth Busters showing his cabinet from a company called Sortimo. Although these are not Sortimo cases, I thought people would like to see my inexpensive version of those cases.
