Used HP mini PCs
HP's business desktops have been sold under the ProDesk and EliteDesk names, with EliteDesk as the higher tier, and both lines include a Desktop Mini (DM) chassis. The EliteDesk 800 G1 was offered in a Desktop Mini chassis in early 2014, and the Mini line continues through models such as the EliteDesk 800 G3 to G6 and the ProDesk 400 and 600 Minis. AMD-based versions use the 705 and 805 names, for example the EliteDesk 805 G6. HP also builds thin clients; the t740, for example, uses an AMD Ryzen Embedded V1756B and has a low-profile PCIe slot. HP's business desktops are also sold under the HP Pro and HP Elite names.
