Desktop PCs are personal computers designed for use at a fixed location, typically placed on or under a desk. They are distinguished from portable computers by larger cases, greater expandability, and often higher performance. A desktop combines a case housing the main components with a motherboard, central processing unit, memory, storage, a graphics processing unit (either integrated on the motherboard or in a discrete card), a power supply, and cooling solutions. Peripherals such as a monitor, keyboard, and mouse are usually connected externally.

Common form factors include ATX, microATX, and mini-ITX motherboards, which determine the size of the case and the number of expansion slots. Desktops can be traditional towers, compact small form factor units, or all-in-one designs that integrate the display with the computer. Upgradability is a key feature: components such as the CPU, GPU, RAM, storage, and fans can typically be replaced or expanded, enabling longer useful lifespans and targeted performance improvements.

Typical operating environments range from home and office to specialized setups for gaming, content creation, or scientific computing. Storage options include hard disk drives and solid-state drives, with NVMe SSDs offering higher speeds. Power supplies are rated for efficiency (for example 80 Plus), and cooling can be air-based or liquid-based, influencing noise and thermals.

Common software includes Windows and Linux distributions; macOS runs on Apple hardware and is not generally used in generic desktop PC builds. Networking is provided via Ethernet and often Wi‑Fi; USB, DisplayPort, HDMI, and audio ports connect peripherals and displays.
