Processor (CPU) — Acts as the "brain" of your computer. In most builds, the CPU is usually the most expensive
component.
Motherboard — Serves as an interface between all of your computer's components and the processor.
RAM — Random Access Memory. More RAM will provide more "workspace" to increase your computer's
performance. Think about the RAM as a table: more RAM gives you more room for doing things on that table. Less
RAM is like having a smaller table!
Storage Drive — Stores data. You can buy a traditional hard disk drive (HDD), or you can opt for a more expensive
solid state drive (SSD) if you want an exceptionally fast drive.
Power supply — Powers all of your computer's individual components. The power supply is also the interface
between your computer and the wall socket into which you plug your computer.
Case — Necessary for storing and cooling your components.
Graphics card — Used to render images on your computer. While most processors have a built-in graphics processing
unit (GPU), you can buy a dedicated graphics card if you plan on gaming or using your computer for intensive editing.
Cooling system — This includes case fans and coolers for specific parts and keeps the inside of your case at a safe
temperature. Only necessary for gaming and editing PCs—regular PCs should be fine with a stock cooler.
