A configurable, dismantlable display case system, with supports for promotional graphics, particularly suited for use as a display cabinet, and with the possibility of changing a promotional campaign thereon as many times as may be necessary, the display case system comprising:

• a shelving unit comprising:
• (i) trays at different levels, wherein the trays are linked at their corners by pillars of a generally triangular profile with rounded corners, which fit adjustedly into corresponding housings in each tray, wherein blind housings are located one at each corner and on upper and lower sides of each tray;
• wherein each tray comprises a flat, horizontal surface of a generally quadrangular shape and with a predetermined thickness, defining a frontal edge, a rearward edge, and lateral edges, and an external wall, perpendicular to the flat surface, and whose medial line is marked by the external line of each horizontal edge of each tray;
• wherein each housing at each corner comprises a generally triangular shape with rounded corners, being visible and functional from both above and below the corresponding tray to which the housing is connected;
• wherein at the center of an upper part of each tray, four housings are defined for pillars closely facing each other;
• wherein each tray further comprises at its corners male-female connecting means to enable the lateral interlocking of corresponding shelving units;
• wherein the male-female connecting means are located vertically at the lateral edges of each tray, at one extremity a female connector and at the other extremity a male connector, at the four lateral edges;
• (ii) pillars for slotting into the triangular housings of each tray (at the corners or centrally) and comprising perforations located spacedly at their sides;
• (iii) short profiles or legs, of a more reduced length than the pillar profiles, of a generally triangular shape with rounded corners which slot adjustedly into corresponding housings of each tray (at the corners or centrally) and also comprise perforations located spacedly at their sides;
• and
• (iv) non-slip ferrules inserted into the profile forming the leg.
