No build log or build pics, sorry. I can provide the following info though:
Floor Cabinet:
I used frameless cabinet construction which relies on the back of the cabinet for strength. I used 1/2" plywood, but would probably go with 3/4" if I were to build more. Its a little flimsy when not nailed to the wall. The back is an entire 4x8 sheet. The cabinet sides are 3/4" oak and is just a full sheet cut in half, plus the cutout for the toe kick. The cabinet floor is also 3/4" oak plywood, and is atop the toe kick (not against the garage floor) much like a kitchen cabinet. I used the following adjustable shelf clips and strips, which were recessed in the cabinet side panels using a dado blade.
I recessed them in the sides so that the shelves could be slid into place, otherwise they would have to be tilted into place since the shelf would need notched for the strips. Since the cabinet back was only 1/2", I couldn't recess the strips so they required notching of the shelf. Functionality isn't affected though. As mentioned earlier, these are the main weakness of my cabinet. I was able to sit on a shelf and it would support me, but over time the clips get weak and pop out if you overload the shelf like my 180lb self. FYI I used 2 strips on each cabinet side, and 2 on the back wall. I would recommend 3 strips on each cabinet side, or a stronger system if you plan on really loading it up. The 2 on the back wall seem sufficient.
The shelves are also 3/4" oak plywood, with 1"x1"x1/4" thick angle iron. This matches the dimensions of the 3/4" plywood well. I drilled, chamfered, and countersunk holes in the angles so that regular construction screws could be used. I applied bondo over the screws for a flush look.
I wanted the large cabinet to house my chargers, so I cut a hole for the wall outlet through the back of the cabinet once I had it fully built and located the cabinet on the wall.
For the doors, I used 3/4" MDF and just bought some self closing hinges off ebay.
Cabinets above workbench:
The small cabinets I built into 3 sections and used the same materials as the large cabinet. I dimensioned them to be exactly 8' long when mounted, so that it matched my workbench length. For the height, I took the 8' tall cabinet height and subtracted both my workbench height and the clearance I wanted from the workbench to the bottom of the cabinet. Off the top of my head, the bench is 36" tall and I wanted 18" clear so that resulted in a 42" tall cabinet. I extended the cabinet sides and bottom front face down 3 or 4" to house the strip lights. Its a similar principle as the large cabinet and the kick plate, in terms of locating the inside cabinet bottom. Once the 3 cabinet sections were complete I screwed them together to make one long unit. They were done because of the recessed lights. They are a bit heavy to hang though.
The light became more of a headache than I thought, mostly to poor planning. I wanted to use 2 four foot T8 housings, but with a cabinet exactly 8' long the housings ended up protruding through the ends of the cabinet. So I cut down a 4'er to create a 3' light, so I have a two bulb 4'er and two bulb 3'er. The ballast is enclosed in the 1' area between the two lights. The light housings I purchased ended up being too deep than I wanted, so I cut them down to be more shallow. Ton of work for lighting, but glad I incorporated it.
As for paint, I used plain ol Rustoleum in a gallon/quart can. It was either the Gloss Smoke Gray or Charcoal Gray, if I'm not mistaken. Its the darker of the two grays they offer, in case I got the wrong color stated. Thinned it and sprayed it from an HVLP gun.
In terms of casters, I personally wouldn't recommend them with a cabinet of this dimension. 8' tall and only 2' deep results in it potentially being pretty top heavy depending on how you load it. With my toe kicks, I can pretty easily tip it forward when unloaded and not screwed to the wall. I would think casters would even further reduce the stability since the footprint is technically smaller. I just moved this cabinet into my new garage a few months ago, so that experience is pretty fresh in my mind.
A tip on installing the cabinets above the bench, they weigh enough that I created an 18" tall scaffold out of 2x4s, so that me and my helper just lifted the cabinet onto this scaffold sitting on my workbench. Essentially 2x4s vertically as columns and 2x4 cross bracing to the columns for stability, and slapped an old sheet of plywood atop it for a smooth flat surface for the cabinet to rest. This allowed me to take my time leveling the cabinet (shimming the scaffold) and screwing the cabinet to the wall.
