There are several devices you might find under the cover of a system unit, also known as a computer case or tower. Here are some of the most common ones:
Motherboard: This is the main circuit board that all other components connect to. It houses the CPU socket, RAM slots, and various connectors for storage drives, graphics cards, and other peripherals.
Central Processing Unit (CPU): Also called the processor, this is the brain of the computer and performs most of the calculations. It sits in a socket on the motherboard and is often cooled by a heat sink and fan.
Random Access Memory (RAM): This provides temporary storage for data that the CPU is actively using. RAM is much faster than storage drives, but data is lost when the computer is turned off.
Storage Drives: These include hard disk drives (HDDs) and solid-state drives (SSDs). They provide permanent storage for data and programs.
Graphics Card (GPU): This is a specialized processor that handles graphics processing and video output. It's essential for tasks like gaming, video editing, and graphic design.
Power Supply Unit (PSU): This converts the incoming AC power from the wall outlet to the DC power needed by the computer's components.
The exact number and type of devices will vary depending on the specific computer model and its purpose.
