Component guide
PC case
Protects and supports internal components. Its layout helps organize cables and allows air to circulate around the parts.
How does it work?
The case provides mounting points for the motherboard, drives, power supply and fans. Its structure organizes components, while intake and exhaust openings refresh the air inside.
Concepts you should know
Key concepts: motherboard size, GPU clearance, cooler height and fan placement. Not every case supports the same components.
An everyday example
A long graphics card may occupy several expansion slots and extend close to the front fans. Internal clearance therefore matters as much as exterior size.
How it connects to the rest of the computer
Must support the motherboard and power supply form factors, as well as the dimensions of the GPU, cooler and installed radiators.
