BACKGROUND 
     1. Technical Field 
     The present disclosure relates to an electronic device with replaceable drive bracket for accommodating hard disk drives of varying sizes. 
     2. Description of Related Art 
     Electronic devices, such as computers and servers, include at least one non-volatile storage device. Examples include hard disk drives (HDD), CD ROMs, and the like. Data and/or programs can be stored on such devices and remains there even if the computers or the servers are powered off. For the sake of simplicity, the following disclosure refers to HDDs, but relates generally to any type of storage device. 
     As is also well known, the memory capacity of an HDD is often dictated by the physical size of the HDD. That is, as magnetic elements used to store the data are increased in physical size or number, the capacity to store data is correspondingly increased. Thus, different brackets for different sizes of HDDs are desired to install the desired size of HDDs in computers and servers.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Referring to  FIGS. 1 and 2 , an embodiment of an electronic device includes a chassis  10 , and a first drive bracket  30  or a second drive bracket  50  installable in the chassis  10  for holding disk drives therein. The first drive bracket  30  is capable of holding a plurality of first disk drives therein. The second drive bracket  50  is capable of holding a plurality of second disk drives therein. The first disk drives are sized different from the second disk drives. In the embodiment, the electronic device is a server. The first disk drives are 3.5″ HDDs, and the second disk drives are 2.5″ HDDs. 
     The chassis  10  includes a bottom panel  11  and a pair of side panels  12  extending perpendicularly upwardly from opposite sides the bottom panel  11 . A pair of limiting protrusions  123  protrudes inwardly from a top portion of each of the side panels  12 . A flange  121  is bent perpendicularly outwards from a front edge of each of the side panels  12 . A pair of securing holes  1211  is defined in the flange  121  of each of the side panels  12 . 
     The first drive bracket  30  includes a first bottom panel  31 , a first top panel  32 , and a pair of first side panels  33  connecting the first bottom panel  31  to the first top panel  32 . Three first dividing panels  34  parallel to the first side panels  33  are disposed in the first drive bracket  30 , thus forming four equal sized first rooms  35  in the first drive bracket  30 . A pair of parallel supporting rails  333  protrudes inwardly from each of the side panels  33 . Each of the first dividing panels  34  defines two rows of first supporting protrusions  341  protruding from a surface thereof. Then each of the first rooms  35  is capable of holding three first disk drives therein. The first disk drives are supportable by the first supporting protrusions  341  and/or the supporting rails  333 . A first flange  331  is bent from each of the first side panels  33  corresponding to the flange  121  of the chassis  10 . Each of the first flanges  331  defines a pair of first securing holes  3311  therein corresponding to the securing holes  1211  of the chassis  10 . Each of the first side panels  33  defines a pair of first limiting recesses  332  therein corresponding to the limiting protrusions  123  of the chassis  10 . 
     The second drive bracket  50  has a structure similar to the first drive bracket  30 . An outer enclosure of the first drive bracket  30  is equal in size to the second drive bracket  50 . The second drive bracket  50  includes a second bottom panel  51 , a second top panel  52 , and a pair of second side panels  53  connecting the second bottom panel  51  to the second top panel  52 . Four second dividing panels  54  parallel to the second side panels  53  are disposed in the second drive bracket  50 , thus forming five equal sized second rooms  55  in the second drive bracket  50 . The second rooms  55  are smaller than the first rooms  35  of the first drive bracket  30 . Four rows of second supporting protrusions  541  are regularly formed on the second dividing panels  54  and the second side panels  53 . Thus, each of the second rooms  55  is capable of holding five second disk drives therein due to the supporting of the second supporting protrusions  541 . A second flange  531  protrudes perpendicularly outwards from each of the second side panels  53  corresponding to the flange  121  of the chassis  10 . Each of the second flanges  531  defines a pair of second securing holes  5311  therein corresponding to the securing holes  1211  of the chassis  10 . Each of the second side panels  53  defines a pair of second limiting recesses  532  therein corresponding to the limiting protrusions  123  of the chassis  10 . 
     Referring to  FIG. 3 , in assembly, if the first disk drives are desired to be installed in the electronic device, the first drive bracket  30  is attached to the chassis  10 . The limiting protrusions  123  of the chassis  10  engage with the first limiting recesses  332  of the first side panels  33  of the first drive bracket  30 . The first securing holes  3311  of the first drive bracket  30  align with the securing holes  1211  of the chassis  10 . Then the first drive bracket  30  can be screwed to the chassis  10  for installing the first disk drives in the chassis  10 . 
     Referring to  FIG. 4 , if the second disk drives are desired to be installed in the electronic device, the first drive bracket  30  is removed from the chassis  10 . The second drive bracket  50  is secured to the chassis  10  for installing the second disk drives.
