2.5'' or 3.5'' to 5.25'' SSD HDD Mounting Bracket Internal Hard Disk Drive Bays Holder Adapter for PC

Bottom line: The 2.5'' or 3.5'' to 5.25'' SSD HDD Mounting Bracket Internal Hard Disk: Fits 3.5" HDD or 2.5" SSD into any open 5.25" bay; main trade-off: holds only one drive - no 2.5" SSD and 3.5" HDD together.
