The 32mm system is a method of assembling cabinet boxes that is now standard for most hardware sold today. In my opinion it is the only way to go for building any sort of cabinetry, large or small, from a single cabinet to multiple production boxes. It is extremely accurate, very quick, and I can assemble with the utmost confidence without double checking any measurements before a cut.
Here's a great little project that packs in a big Arts and Crafts punch. It's a scaled-down version of an Arts and crafts display case that I had originally built for Fine Woodworking. It incorporates the same features as the original, but requires less lumber and effort to build.
