I wouldn't trade my metal storage cabinets for anything. The drawers contain dividers that can be rearranged, labeled, and are insanely strong (440 lbs/drawer) and roll as smooth as silk. These ones are Lista Cabinets. There's others that are similar. The one shown stores just hardware. Others store tools, electrical supplies, casters, sandpaper, shaper cutters, etc... One day I'll get around to labeling things (hopefully sooner than later) and build a maple top for them.

The best thing about organizing my hardware, is that I always know exactly where everything is, and if something starts to get low, I can notice it and buy more stock the next time I'm in town. I rarely have to make a special trip to the hardware store for hardware any more.
