This cabinet is actually pretty simple as it only has four essential components, a Side, Back, Top and Bottom with optional Adjustable shelves. The side is the depth of the cabinet, and the back is identical to a side except that is it 19mm (3/4") narrower to but into the cabinet Side.
If you need doors on this cabinet, you will need to use the negative angle hinges listed in the "What Hinge and Hinge Plate should I use?" question of the Functional Hardware group on this page.
Here is a quick animation that hopefully will make this cabinets construction and assembly a little clearer.
