HP ProDesk 400 G6 SFF

This refurbished small-form-factor desktop ships with an Intel Core i7-9700 eight-core processor running at 3.00 GHz and 12 MB L3 cache. It includes 16 GB of DDR4 memory and a 256 GB M.2 NVMe SSD. Windows 11 Pro 64-bit is pre-installed and Intel UHD Graphics 630 handles integrated video output.

Office teams needing a compact Windows 11 machine

The 3.70 x 10.60 x 11.70 inch chassis suits tight desks and standard office workloads such as document editing, web apps and video calls. Buyers who require a discrete graphics card, additional internal drive bays or a full-height expansion slot should look elsewhere.

Build considerations for the SFF chassis

Two front USB 3.1 Gen 1 ports and one audio jack give quick peripheral access. Rear connectivity adds VGA, DisplayPort 1.2, four USB 2.0 ports, two more USB 3.1 Gen 1 ports, RJ-45 and two audio jacks. The integrated graphics frees the single low-profile slot for other add-in cards while the NVMe drive leaves the 2.5-inch bay available for extra storage.
