A computer case includes a housing, a first sub housing, and a second sub housing. The housing includes a bottom wall, a sidewall and a fixing wall extending perpendicularly from the bottom wall, all of which cooperate to form a receiving space. The first sub housing is configured for receiving a redundant power supply. The second sub housing is configured for receiving a single power supply. Each of the first sub housing and the second sub housing is capable of being detachably received in the receiving space and secured to the housing.
1. A computer case, comprising:
a housing comprising a bottom wall, a sidewall extending perpendicularly from a side of the bottom wall, and a fixing wall extending perpendicularly from the bottom wall, wherein the fixing wall is parallel to the sidewall, all of the bottom wall, the sidewall, and the fixing wall cooperate to define a receiving space;
a first sub housing configured for receiving a redundant power supply, the first sub housing comprising a first top wall, a first bottom wall, two first sidewalls and a middle wall, the two first sidewalls and the middle wall connecting the first top wall to the first bottom wall, all of the first top wall, the first bottom wall, the two first side walls, and the middle wall cooperating to define two first sub receiving spaces; and
a second sub housing configured for receiving a single power supply, the second sub housing comprising a second top wall, a second bottom wall, two second sidewalls connecting the second top wall to the second bottom wall, all of the second top wall, the second bottom wall, and the two second sidewalls cooperating to defining a second sub receiving space; wherein
a width of the first sub housing is equal to that of the second sub housing and is equal to that of the receiving space, a length of each of the first sub housing and the second sub housing is equal to or shorter than that of the receiving space; and
each of the first sub housing and the second sub housing is capable of being detachably received in the receiving space and secured to the housing.
2. The computer case of claim 1 , wherein the housing further comprises a second fixing wall extending perpendicularly from the bottom wall, and the second fixing wall perpendicularly intersects the sidewall and the fixing wall.
3. The computer case of claim 1 , wherein the first sub housing comprises a box-shaped main body and a support board extending from one end of the box-shaped main body.
4. The computer case of claim 1 , wherein each of the two first sub receiving spaces is open at two ends.
5. The computer case of claim 1 , wherein the second sub receiving space is open at two ends.
6. The computer case of claim 1 , wherein the sidewall and the fixing wall of the housing define fixing holes, each of the first sub housing and the second sub housing defines screw holes spatially corresponding to the fixing holes for allowing screws to extend therethrough to fix the first sub housing or the second sub housing on the housing.
