Like the power supply, the storage is another component that is not directly installed onto the motherboard. Each computer case comes with a 5.25 accessory rack in which you will install your storage (HDD or SSD).
Using 2-4 screws (depending on the case), secure the storage into the storage trays that are associated with the accessory rack. After doing so, slide the tray into the rack and secure the rack by using the two thumbscrews provided.
