Abstract: A computer case accommodating hardware devices which is secured thereto. The computer case has a base, two side supports, front and rear panels, a cover. A main circuit board of the computer is laid on the base. The supports extend along a direction substantially perpendicular to the base. The front and rear panels are positioned on the front and rear of the base, respectively. The cover covers the internal devices of the computer. Each structure is configurated to have a uniform sectional shape.

Abstract: Disclosed are various constructions of a computer case. A disclosed computer case includes a plurality of external walls, each external wall comprising a substantially planar external surface, an internal surface and a plurality of edges. In this computer case, each edge of each external wall is connected to an edge of a neighboring external wall so as to construct a housing configured to enclose electronic circuits of a computer. External surfaces of a pair of neighboring external walls are not in a single plane. At least one of the external walls includes two or more single-piece wall elements. Each wall element has a substantially planar external surface and an internal surface, and the two or more wall elements are so arranged as to form one of the external walls.
