When two computer housing want to be stacked to be close to the volume of one computer housing, the first panel, the first right side plate and the first left side plate are respectively detached from the computer housing, and the upper cover is caused to detached from one of the main structure, and the lower cover is caused to detach from another one of the main structures. Thereafter, the computer housings are allowed to be stacked together.
The first side edges 121 and 131 of the first front and the first rear walls 12 and 13 are respectively combined to front and rear edges of the first motherboard blocking wall 14. The first front and rear walls 12 and 13 and upper and lower edges of the first motherboard blocking wall 14 are respectively combined with the first upper cover 11 and the first lower cover 19. A first side edge 151 of the first left supporting frame 15 is pivotally connected to a second side edge 122 of the first front wall 12 through a first hinge 152 as FIG. 2 shows. The first right upper supporting frame 16 and the first right lower supporting frame 17 are respectively combined with an inner side of the first motherboard blocking wall 14. The first right upper supporting frame 16 is located above the first right lower supporting frame 17. Finally, the first power supply 18 is combined with an upper edge of an inner side of the first rear wall 13.
When the first main structure 10 is contracted, a second side edge 153 of the first left supporting frame 15 is propped against the first front wall 12 as FIG. 1 shows. When the main structure 10 is expanded, the second side edges 153 of the first left supporting frame 15 is expanded to a position opposite to a second side edge 132 of the first rear wall 13 as FIG. 2 shows. In the meantime, the first left supporting frame 15 is opposite to the first right upper supporting frame 16 and the first right lower supporting frame 17. A space between the first left supporting frame 15 and the first right upper supporting frame 16 is used for accepting a first kind electronic device such as a 5.25 inch CD-ROM drive and a space between the first left supporting frame 15 and the first right lower supporting frame 17 is used for accepting a second kind electronic device such as a 3.50 inch CD-ROM drive.
