The HP Desktop Mini v4+ VESA Sleeve with Power Supply Holder (99T55AA) is a steel mounting sleeve that secures an HP Desktop Mini PC and its external power supply to a monitor, wall, desk or any VESA-compatible arm, freeing up desk space and keeping the computer out of sight. The sleeve encloses the Mini PC while an integrated holder takes the power brick, so the whole assembly hangs neatly behind the screen. It is aimed at offices, hot-desking areas, kiosks and point-of-sale counters built around HP's small-form-factor desktops. HP includes everything needed to install it: the security/dual VESA sleeve itself, two sets of Torx T15 screws, a set of 20 mm Phillips #2 screws, 7 mm and 2 mm spacers, and an installation guide. The unit is finished in black, measures about 185 x 163.3 x 45 mm and weighs roughly 405 g. The v4+ designation refers to HP's current Desktop Mini sleeve generation; check your Mini model's compatibility with HP before ordering. It is covered by HP's standard one-year limited warranty. Note that the product listing files this under Laptop Bags, but it is a mounting bracket.
