There are two main types of brackets used in PCs, each serving a distinct purpose:

1. Mounting brackets:

  • Description: These are metal frames used to secure various PC components within the case. They come in various shapes and sizes depending on the components they hold.
  • Function: They prevent components from moving around during operation, provide stability, and maintain proper airflow within the case.
  • Examples:
    • Motherboard mounting bracket: This large bracket secures the motherboard to the case and allows for connections to peripheral devices like storage drives and expansion cards.
    • Drive bay brackets: These smaller brackets secure various storage drives (like hard drives and SSDs) within designated bays in the case.
    • Fan brackets: These brackets hold cooling fans in position, directing airflow toward specific components like the processor or graphics card.

2. Expansion brackets:

  • Description: These are metal slots on the back of the computer case. They come in a standardized size and shape called PCI-e (Peripheral Component Interconnect Express).
  • Function: Expansion brackets allow users to add additional functionality to their PCs by installing expansion cards like graphics cards, network cards, or sound cards.
  • Examples:
    • Full-length PCI-e x16 slot: This is the largest and most powerful slot, typically used for high-performance graphics cards.
    • PCI-e x1 slot: This is a smaller slot often used for network cards or other low-bandwidth add-on cards.

Remember, these are just two main categories of brackets used in PCs. There might be other specialized or specific types depending on the individual PC case and its components.
