HP ProDesk 400 G5 SFF desktop PC, 27" monitor, i3-8100 3.6GHz, 8GB DDR4, 1TB SSD, Windows 11 Pro

Compact Business Desktop with 27" Display

The HP ProDesk 400 G5 SFF pairs an Intel Core i3-8100 running at 3.6 GHz with 8 GB of DDR4 2666 memory and a 1 TB SSD. A new 27 inch FHD monitor, keyboard and mouse are included so the system is ready for office productivity, video calls and light development work straight out of the box. Windows 11 Pro comes pre-installed on the solid-state drive. The small form factor chassis fits easily on a crowded desk or behind a monitor arm.

Installation and Common Issues

The unit arrives assembled; simply connect the monitor cable, plug in the keyboard and mouse, and attach the power cord to the 180 W supply. Wireless networking and Bluetooth are provided by a USB adapter that occupies one port. The slim case limits internal expansion to low-profile cards only, and the proprietary motherboard layout prevents standard ATX upgrades. BIOS updates should be applied before deploying custom images to avoid boot-order surprises.

Sustained-Load Behaviour

Under continuous multi-threaded workloads the quad-core processor maintains its 3.6 GHz base frequency while the air-cooling system keeps temperatures stable. Integrated Intel UHD Graphics 630 handles extended video playback and multiple browser tabs without throttling. The 1 TB SSD delivers consistent read and write speeds during long file transfers or database operations. Fan noise remains low and predictable throughout an eight-hour workday.
