The HP EliteOne G9 VESA Plate (6H1W8AA) is an adapter plate that lets you take the HP EliteOne 800 G9 all-in-one PC off its standard stand and mount it on a wall bracket or a monitor arm using the common VESA hole pattern. It is used where desk space is tight, such as reception counters, hospital and clinic workstations, call centres and shared hot desks, where an arm-mounted AiO frees up the work surface. HP also lists it for the HP Elite Slice for Meeting Rooms. The plate attaches to the back of the computer in place of the stand and presents VESA mounting holes for your arm or bracket, which is sold separately. It measures 120 x 117.5 x 49.9 mm and weighs 480 g, and ships in a box of 168 x 140 x 60 mm. HP covers it with a one-year limited warranty. Check the load rating of your arm against the weight of your EliteOne model before mounting.
