Referring to FIGS. 1 and 2, a computer chassis for mounting a motherboard 30 therein, includes an enclosure 10.

The enclosure 10 includes a bottom plate 11 and a rear plate 13. The rear plate 13 is perpendicularly connected to a rear edge of the bottom plate 11. A plurality of convex projections 12 is protruded from the bottom plate 11. Each of the plurality of convex projections 12 defines a first mounting hole 121. The plurality of convex projections 12 can support the motherboard 30 thereon. The bottom plate 11 further includes a plurality of first restricting pieces 15 and a plurality of second restricting pieces 14 located thereon. The plurality of first restricting pieces 15, the plurality of second restricting pieces 14, and the rear plate 13 together surround a mounting area 18 on the bottom plate 11. The plurality of first restricting pieces 15 and the rear plate 13 are located on opposite two edges of the mounting area 18. The plurality of second restricting pieces 14 are located on another opposite two edges of the mounting area 18. The plurality of convex projections 12 are located in the mounting area 18.

Referring to FIGS. 2 and 3, each of the plurality of first restricting pieces 15 is perpendicularly connected to the bottom plate 11. An edge of each of the plurality of first restricting pieces 15 which faces the mounting area 18 is rounded, and an arc-shaped first guiding piece 151 is connected to the rounded edge. The first guiding piece 151 is perpendicular to each of the plurality of first restricting pieces 15.

Referring to FIGS. 2 and 4, each of the plurality of second restricting pieces 14 is perpendicularly connected to the bottom plate 11. A top edge of each of the plurality of second restricting pieces 14 is bent away from the mounting area 18 to form a second guiding piece 141 thereon. The second guiding piece 141 is arc-shaped.

Referring to FIGS. 1 and 2, the rear plate 13 defines a plurality of cutouts 131.

The rear edge of the motherboard 30 is equipped with a plurality of ports 32. A plurality of second mounting holes 31 is defined in the motherboard 30 corresponding to the first mounting holes 121 of the bottom plate 11.

Referring to FIGS. 1 to 6, to mount the motherboard 30 in the enclosure 10, the rear edge of the motherboard 30 is inclined to align the plurality of ports 32 with the plurality of the cutouts 131 of the rear plate 13. Then, the motherboard 30 is rotated around the rear edge while left and right edges of the motherboard 30 slide along the second guiding pieces 141 of the plurality of second positioning pieces 14. The front edge of the motherboard 30 slides along the first guiding piece 151 of each of the plurality of first restricting pieces 15. The motherboard 30 is rotated until the plurality of convex projections 12 support the motherboard 30 thereon. At this position, the rear edge of the motherboard 30 abuts the rear plate 13. The front edge of the motherboard 30 abuts the plurality of first restricting pieces 15. The left and right edges of the motherboard 30 abut the plurality of second restricting pieces 14. The plurality of second mounting holes 31 of the motherboard 30 are aligned to the first mounting holes 121. Then, a plurality of fasteners 70 can be easily secured in the plurality of second mounting holes 31 and the first mounting holes 121 to secure the motherboard 30 in the enclosure 10.

In the computer chassis, the first guiding piece 151 and the second guiding piece 141 can guide the motherboard 30 to slide into the correct position where the plurality of first restricting pieces 15 and the plurality of second restricting pieces 14 can conveniently keep the motherboard 30 in the correct position where the first mounting holes 121 and the plurality of second mounting holes 31 are aligned, while fasteners are installed. The first guiding piece 151 and the second guiding piece 141 are arc-shaped to prevent scratching the motherboard 30.

It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
