They're actually these Stalwart branded organizers off Amazon. I have a price watch set, and all of the ones you see pictured I bought for about $25 for the set of 4. They only pop up for that price every so often on Amazon, so this is what I've accumulated after about 2 years of slowly buying them.

They're dimensionally the same as the Harbor Freight small parts organizers, but they're a little higher quality. At $25 for the 4 pack they're also cheaper than the Harbor Freight ones, except you have to buy them in the 4 pack, so I end up with more of the "deep" boxes than I really need. I've been trying to come up with more uses for the deep ones, I have about 5 empty ones right now.

But even at that price I have about $300 worth of those organizers in this picture. Each cabinet is about $200 worth of plywood at today's prices, plus I have probably $80 worth of Akro-Mils bins inside each cabinet. It takes a lot of time and money to be organized :-\.
