Zotac ZBox Q Series (QK7P5000)

Compact design. Exceptionally powerful graphics card for a system this size. Ample port selection, including four video outs. Available as a barebones unit. Accepts two drives (one M.2, one 2.5-inch).

While still powerful, some components are outdated. Not VESA-mountable. Limited upgradability.

Bottom Line: While Zotac's ZBox QK7P5000 mini workstation has remarkable graphics performance for such a diminutive desktop, it needs a more powerful processor to compete against the HP Z2 Mini G4.
