Also known as: AIO, All-in-one PC

An all-in-one computer (AIO) integrates the whole computer — processor, memory, storage, and other components — into the same enclosure as the display, so the only things on the desk are a keyboard, a mouse, and a power cable.1

An all-in-one folds the computer behind the screen: the CPU, RAM, and storage live in the same shell as the panel, so setup is one cable and one box — at the cost of the modular internals a tower exposes.

Overview

An AIO is a personal computer that trades the modular tower of a desktop computer for a single tidy unit. To fit the whole machine behind the screen it usually borrows laptop-class parts: low-power CPUs, soldered or limited RAM, and integrated graphics rather than a discrete card.

The best-known example is Apple’s iMac, but most major PC makers ship AIO models aimed at homes, offices, and public-facing counters. The upside is a clean desk and near-zero setup; the downside is limited upgrades and a shared fate — a screen failure can take the whole computer with it, and a slow CPU can’t be swapped the way it can in a tower.

Form factors

An AIO sits between a laptop and a tower — desktop-sized screen, laptop-grade internals, no portability:

Machine Screen Upgradeable Desk footprint Typical parts
All-in-one Built in Very limited Small (one unit) Laptop-class
Desktop tower Separate Extensive Large Full desktop
Mini PC Separate Limited Tiny Laptop-class
Laptop Built in Minimal Portable Laptop-class

Where it fits

An all-in-one suits reception desks, kiosks, classrooms, and homes where appearance and simplicity matter more than expandability or raw performance. If you want to upgrade parts later, a desktop tower or even a small mini PC paired with a separate monitor gives more freedom; for a portable machine, a laptop is the natural choice. For a GopherTrunk bench an AIO works as the display-and-host in one, though its soldered memory and integrated graphics leave less headroom than a tower for many-channel decoding.
