Here are the ones I put in my wifes building. They're plenty sturdy. Although she has them all painted white now. IIRC, I think we only had maybe $300 give or take a small amount in them.
I did have these in my garage, but I ended up giving them to a friend as he didn't have anything in his garage. He always helped me out when I needed help on doing something, so this was some of the payment for him helping me. I do sort of miss them though as there was a lot more storage room. But when I jumped in on the Gladiator overhead cabinet sale, I bought 18 of the Gladiators and got rid if these. And to let ones know, I didn't have a lot in them. The doors I bought for $5 each. The overheads are made out of 1" x 12" shelving pine, and either 1" x 3" or 1" x 4" pine fronts. The doors are oak and were already finished. There are quite a few places around that sells cabinets doors. A lot of them have been misdrilled for hinges, or the grain don't quite match for a quality kitchen, so the factories unload them to people that buys them up in quantities, then resells them. Just the other day, someone on CL has over 25,000 doors in stock to sell.
The lower cabinets are just 2" x 4" framing, with 1" x 3" or 1" x 4" for the fronts. I put a piece of OSB on the top and added doors on the ends.
Technically not kitchen cabinets per se, but would work in a kitchen with a little upgrading.
