I have a lot of tools ranging from nice heavy stuff like the TS/75 track saw, Masonry dril, ... to delicate machinist instrumentation like Mtu mics and such, and the electronics lab instrumentation I use as an engineer like scopes and meters, and just about everything in between, hand tools and so forth. For years I was losing time just finding stuff and reorganizing it. After looking for acceptable tool cabinets according to my OCD-type specs and finding none, and after having gone through that cycle of bins and shelves, and just about giving into paying Snap-On to build a custom-designed cabinet, I settled on adapting a heavy-duty steel shelf unit from uline. 60-in W * 24-inch D * 72-inch H. I am bolting non-flexible heavy gauge stainless steel siding on the sides and back inside the L-shaped four uprights for closed shelvs, and setting boxes in and along the shelves to act as drawers on side mount heavy double sides. Sounds clunky, but I can alter drawer levels and heights when I want which is likely almost never, I can set up precise sizes and levels for categories of tools and instruments and lots of room to boot, the thing is strong strong strong, and I can customize its drawer sizes. The whole thing is strong, solid and configurable. Still haven't fully settled about the drawer fronts and the locking but so be it for now. On the bottom will be either shelves for the heavy power tools in their nice cases 16.5-inch height, or two drawers if I can swing it. I prefer my shop stuff in levels according to their uses, and the tool cabinets and chests out there seem to have a mishmash of drawer sizes and banks all mixed together. So far working out fine, although I haven't yet settled on an ideal straight wall drawer/box style, but lots out there from which to choose or build. I might reduce the height of the four uprights which I think are 14-gauge from 72 inch to about 52 or 54 inch. I can always reaffix lengths if I want to reclaim height.
