The HP B300 Bracket with Power Supply Holder (7DB37AA) lets you mount a compact HP computer directly behind a compatible HP monitor, turning a desktop and display into a tidy, space-saving workstation with no separate box on the desk. HP designed it for HP Desktop Mini PCs, HP Chromeboxes, select HP Thin Clients and small HP Workstations, and it attaches behind select HP EliteDisplay and HP Z Display monitors using the monitor's VESA mounting points. A lower cradle holds the computer's external power supply as well, so the power brick is not left hanging from its cable. HP lists compatibility with a long run of Desktop Mini models, including the HP 260 G2 and G3, ProDesk 400 G4/G5, ProDesk 405 G4, ProDesk 600 G3/G4/G5, EliteDesk 705 G4 (35 W and 65 W) and EliteDesk 800 G4/G5. It is a passive steel holder finished in black for indoor use, measuring about 160 x 96.5 x 246.3 mm and weighing roughly 917 g, and carries HP's one-year limited hardware warranty. It suits offices, reception desks, call centres and classrooms standardising on HP mini desktops.
