HP ProOne 400 G3 All-in-One PC Intel Core i5 7500T 2.70GHz 8GB DDR4 500GB HDD 20

HP ProOne 400 G3 All-in-One

This 20-inch all-in-one desktop integrates a 7th Generation Intel Core i5 7500T processor running at 2.70GHz with 8GB of DDR4 memory and a 500GB hard drive. It ships with Windows 10 Pro 64-bit and includes a keyboard and mouse. The non-touch display uses Intel HD Graphics 630 for everyday visual tasks. It suits small offices or home workspaces needing a compact, cable-reduced setup.

Check display size and storage type

Verify that a 20.0-inch screen diagonal meets your workspace viewing requirements before purchase. Confirm that a mechanical 500GB hard drive provides sufficient capacity and speed for your intended applications. Ensure the pre-installed Windows 10 Pro 64-bit operating system aligns with your software compatibility needs. The integrated Intel HD Graphics 630 handles standard business and web workloads.

Upgrade from older all-in-ones or separate towers

This unit replaces ageing all-in-one PCs that lack 7th Generation Core performance or DDR4 memory. It also consolidates a traditional tower-and-monitor pair into a single 20-inch device, reducing desk clutter. The jump is worthwhile when you need Windows 10 Pro on a space-saving platform with included peripherals. Buyers requiring a larger 23.8-inch panel, touchscreen input, or solid-state storage should consider other models.
