The essential list
A typical build needs a processor, motherboard, memory, storage, power supply and case. It also needs cooling, although some processors include a suitable cooler.

When you need graphics
A dedicated graphics card is important for demanding games, rendering and GPU-accelerated work. For basic productivity, a processor with integrated graphics may be enough.
Parts outside the case
A complete setup also needs a display, keyboard and mouse. Audio, networking, a webcam and backup power depend on how and where the computer will be used.
Avoid buying parts in isolation
A powerful part can still be a poor choice if it does not fit, connect or balance with the rest of the machine. Build the complete configuration before purchasing.
Common questions
Does every PC need a CPU cooler?
Yes, the processor needs cooling. Some retail CPUs include a cooler and others require one to be purchased separately.
Can I use any motherboard with any CPU?
No. The socket, chipset and BIOS support must be compatible with the exact processor.
