CPU Cooler – Helps dissipate heat from the processor to ensure optimal performance.



Motherboard – Serves as the bridge connecting all PC components.



RAM (Memory) – Temporarily stores data to speed up program execution.



Storage (SSD/HDD) – Stores system files and user data.



Graphics Card (GPU) – Handles graphics processing for gaming, video editing, and rendering tasks.



Power Supply Unit (PSU) – Provides power to all components.



PC Case – Houses all components, offering protection and extending the system’s lifespan.
