What are risers used for?
Risers are printed circuit boards that increase connectivity options in a computer or a server. Typically connected to PCIe or MCIO ports, they extend the connection between a motherboard and components like graphics cards, storage drives, or other peripherals.
Their use is not limited to changing existing outputs; they also allow the relocation of the original port to another location, freeing up space inside the tower or server. This creates room to accommodate a greater variety of components.
The main purposes are:

Cable Management
Provide more flexibility in cable routing, which helps improve system organization and cleanliness.

Enabling Multiple Components
Allow the installation of more GPUs or cards in a system, especially in high-performance servers or workstations.

Heat Management
By positioning components differently using risers, it can improve airflow, reducing heat buildup and enhancing cooling efficiency.

Space Optimization
Allow components like GPUs to be mounted horizontally or in different positions, making better use of limited space within a server rack or gaming case.
