Compact business desktop with integrated display

The HP ProOne 400 G1 combines a 19.5-inch HD+ screen with a quad-core Intel Core i5-4570T at 2.9 GHz, 8 GB of DDR3 memory and a 500 GB SATA hard drive. Windows 10 Pro 64-bit is pre-installed alongside a DVD-RW drive, webcam and wired keyboard and mouse. It targets office workers and reception desks that need a tidy, single-unit workstation.

1600 x 900 panel and legacy wireless limits

The built-in display tops out at 1600 x 900 resolution, so modern multi-window layouts feel cramped compared to full-HD screens. Wireless support stops at IEEE 802.11n, ruling out 5 GHz AC or AX speeds and making congested offices a bottleneck. Integrated Intel HD Graphics 4600 shares system memory and cannot drive a second high-resolution monitor.

Replaces tower-plus-monitor sets for basic admin

This all-in-one displaces a separate tower and monitor where desk space is tight and workloads stay within web apps, email and document editing. The jump is worth it only when physical footprint matters more than storage speed or graphics headroom; buyers who want more storage, faster memory or discrete graphics should look elsewhere.
