HP Desktop Mini LockBox V2

The HP 3EJ57AA is a lockable enclosure made from solid metal that protects your HP Desktop Mini PC whenever the system sits in an open or shared environment.

Its tamper-resistant construction deters theft and casual interference. The interior has room for the PC itself, the power brick, and any excess cabling, so everything stays tidy and out of sight. At roughly 10.7 inches wide, 10.6 inches tall, and only 2.3 inches deep, the housing delivers dependable protection without adding noticeable bulk.

Installing the unit is straightforward because it follows the standard VESA mounting pattern. You can attach it to a wall, the back of a monitor arm, or the underside of a desk with the same screws you already use for displays and brackets. Once secured and locked, you have a compact package that keeps peripherals connected while preventing anyone from unplugging or removing the computer.

The enclosure accepts a broad range of HP models, including the ProDesk 400 and EliteDesk 800 series. With a weight of about 5.17 pounds and a 5-year limited warranty, it offers a long-term answer for IT teams that need to safeguard equipment in offices, classrooms, retail counters, library terminals, or any other high-traffic area.

Whether you want to keep a check-in kiosk running, protect a demo station at a trade show, or simply stop household members from moving the living room PC, this lockbox delivers the peace of mind that comes from reliable, physical security.
