Computer Hardware
Case
Definition
A computer case, also known as a computer chassis, tower, system unit, or cabinet, is the enclosure that contains most of the components of a personal computer (usually excluding the display, keyboard, and mouse).
Why It Matters
The case protects the delicate internal components from dust, physical damage, and static electricity. It also plays a crucial role in cooling by directing airflow over hot components.
Contextual Example
PC builders choose a case based on its size (to fit their motherboard's form factor), cooling performance (airflow design, fan mounts), and aesthetics.
Common Misunderstandings
- The case is often mistakenly called "the CPU" or "the hard drive" by non-technical users.
- Cases come in various sizes, such as full-tower, mid-tower, and small form factor (SFF).
