Thank you for viewing. This item is a stand for HP Mini PC, an accessory for the ProDesk 400 G6 Mini. It has the PI-747923 marking on the back. I mounted it on the back of a display, so I no longer need it. The packaging is crumpled, but it has been stored unopened and unused. It may also be compatible with ProDesk 400 G5 Mini, etc., but please confirm this yourself. I hope someone looking for this item will find it. Thank you.
