Abstract: The main body of the present invention, an extruded aluminum computer case structure with connecting sheets, is composed of frame members extruded from one-piece aluminum. On each rectangular side of the frame members forms a convex-shaped end-to-end slot with symmetric extruded sliding rails on both walls and a concave base. A connecting plate with several bolt holes is inserted in the slot and moves freely on the sliding rails, which is interlocked with L-shaped connecting plate by bolts in order to assemble frame members into different combinations. Moreover, the free sliding style of the connecting sheets in the slot helps to enhance the extension of the entire framework, an open computer case structure is formed, which is the purpose hereof.

Abstract: The display-oriented computer casing of the invention includes a front panel, a rear panel, a left panel, a right panel, a top panel, a bottom panel, two partition panels and a plurality of combining members and screws; wherein the aforesaid panels and combining members are made of acrylic materials for revealing a panel design that is multi-color and transparent at one's choice, and for further showing a delicate visual effect through illumination, thereby mostly directly presenting the interior of the computer casing as well as achieving artistic and coordinative purposes.
