13 . The information processing system of claim 12 , wherein the second wall of the filler includes a keyhole, and

wherein in the second installation configuration, the first frame attachment feature penetrates through the keyhole into an interior space of the filler allowing the second wall of the filler to move beyond the first vertical position and allowing the second filler attachment feature to engage with the second frame attachment feature.

14 . An adjustable support assembly of a drive cage of an information processing device, comprising:

a mounting cage configured to attach to a chassis of an information processing device and to interchangeably receive a plurality of module housings attached thereto, each of the module housings configured to receive at least one pluggable module; and

a filler configured to be attachable to the mounting cage in a plurality of installation configurations,

wherein, on condition of one of the module housings being attached to the mounting cage, an unoccupied portion of the drive cage is defined between the module housing and the mounting cage,

wherein a size of the unoccupied portion is variable depending on which of the module housings is attached to the mounting cage,

wherein the filler is configured to, when attached to the mounting cage, extend a distance across an opening of the unoccupied portion, wherein the distance is variable dependent upon which of the installation configurations the filler is attached in,

wherein the mounting cage comprises a frame portion,

wherein the frame portion comprises a plurality of frame attachment features configured to individually engage with the filler to attach the filler to the frame portion in respectively corresponding installation configurations of the installation configurations, and

wherein the frame attachment features have mutually different vertical positions relative to a top plate of the frame portion.

15 . The adjustable support assembly of claim 14 , wherein the module housings each have a first dimension and the first dimensions of the respective module housings vary among the module housings such that the size of the unoccupied portion is variable depending on which of the module housings is attached to the mounting cage.
