ProDesk 400 G6-SFF Business Desktop

The HP ProDesk 400 G6-SFF is a small-form-factor business desktop powered by an Intel Core i5-8400 2.80 GHz six-core processor with 9 MB L3 cache. It ships with 16 GB DDR4 memory and a 256 GB 2.5-inch SSD. Integrated Intel UHD Graphics 630 drives video output through D-Sub and DisplayPort 1.2. Windows 11 Pro 64-bit comes pre-installed.

Suits Office Work; Not for Heavy Graphics

This system suits office workers handling documents, spreadsheets, web apps and video calls in a compact chassis. The small form factor limits internal expansion, so buyers who need a discrete graphics card, additional drive bays or full-height add-in cards should look at a larger tower platform. The integrated GPU handles dual-monitor productivity but cannot accelerate 3D rendering or modern gaming workloads.

256 GB 2.5-inch SSD Capacity

The single 256 GB 2.5-inch SSD determines how much local data the desktop can store before you must add external storage or replace the drive. Windows 11 Pro and typical business applications will consume a portion of this space immediately. If your workflow requires large local datasets, media libraries or multiple virtual machines, the capacity will fill quickly and an additional drive will be necessary.
