What Is a "20 Computer"?
A 20-inch all-in-one (AIO) computer is a desktop where the display, motherboard, storage and ports are housed in a single chassis — no separate tower required. HP's All-in-One 20 series is a well-known example of this format. Models in the HP 20-c family typically pair a 19.5-inch HD+ (1600 x 900) flat panel with an entry-level processor, integrated graphics, a built-in webcam, and a DVD Super Multi optical drive, running Windows 10 Home at launch.
Typical Specifications of HP 20 All-in-One Models
The HP 20-c series spanned several configurations over its life. Public specification pages list variants with AMD E-series processors at around 1.8 GHz, Intel Pentium quad-core chips, and Core i3 options. Memory ranged from 4 GB DDR3L/DDR4 up to modest upgrades, and storage was usually a 500 GB or 1 TB mechanical hard drive. Connectivity centred on USB, HDMI out, and Gigabit-class Ethernet on most SKUs.

Where 20-Inch All-in-Ones Fit
These machines were designed for light, everyday workloads: web browsing, email, document editing, video streaming, point-of-sale terminals, reception desks, and classroom or kiosk deployments. The compact footprint and single-cable setup make them easy to place on a counter or small desk. Because the panel is only 19.5 inches with HD+ resolution, they are not suited to CAD, video editing, or multi-window professional work.
What to Look For in a Modern Replacement
If you are sourcing new hardware for the same roles today, the priorities have shifted. Look for a fanless or low-noise design for dusty or 24/7 environments, an SSD rather than a spinning disk, at least 8–16 GB of RAM, dual display outputs, and a current-generation Intel processor for better performance per watt and a longer supported service life. An industrial-grade chassis with wide-temperature tolerance and long-term supply availability matters more than ever when a device sits in a shop, factory or clinic for years.
Thinvent Products in This Category
Thinvent builds all-in-one PCs, mini PCs, thin clients and industrial computers for exactly these deployments. Where a 20-inch AIO was once used at a counter or kiosk, a Thinvent all-in-one or fanless mini PC offers a current Intel platform, SSD storage, Windows 11 Pro or Ubuntu Linux 24.04 LTS, and a sealed, serviceable design that keeps running through dust, heat and continuous operation. For serial-equipped equipment such as POS peripherals, label printers or legacy controllers, Thinvent industrial PCs with multiple DB9 serial ports provide a direct path forward. Explore the range to match the form factor, processor and operating system to your workload.

The Thinvent Industrial PC IPC3 is the closest available match, offering a comparable compact desktop-class form factor with a significantly more modern 12th-gen Intel Core i3 processor, more RAM, and faster storage than the HP 20 All-in-One. The honest trade-off is that the HP 20 is an all-in-one unit with a built-in 19.5" display, while the Thinvent IPC3 is a standalone industrial PC that requires an external monitor. For customers who already have a display or need a rugged, long-lifecycle system, the IPC3 delivers a strong, current-generation alternative.
