HP ProDesk 400 G5 Mini — Brand-New, Open-Box Windows 11 Pro Desktop

A genuinely brand-new, open-box HP ProDesk 400 G5 Desktop Mini, backed by a Reboot IT 12-month warranty. This is factory-fresh hardware in opened retail packaging — not a used or refurbished machine. It pairs a quad-core Intel Core i3-9100T processor with 16GB of DDR4 memory and a fast 128GB NVMe SSD running Windows 11 Pro, ready for office, study and home productivity straight out of the box.

Key Benefits

• Brand-new, open box: factory-new hardware at a smarter price — never put into service, simply supplied in opened packaging.
• Genuinely compact: the ultra-small ~1-litre chassis tucks behind a monitor or onto a shelf, freeing up your desk.
• Fast everyday response: a 128GB NVMe SSD delivers quick boot times and snappy app loading versus an old hard drive.
• Comfortable multitasking: 16GB of DDR4 RAM keeps browser tabs, email and Office documents running smoothly side by side.
• Dual-monitor ready: DisplayPort outputs and integrated Intel UHD 630 graphics drive two screens for a productive workspace.
• Windows 11 Pro included: modern security, BitLocker and remote-desktop features come pre-installed and genuine.

Performance In Use

For day-to-day business and home computing, this ProDesk 400 G5 Mini hits the sweet spot. The quad-core i3-9100T handles web browsing, email, video calls and Microsoft Office without fuss, while the NVMe SSD means Windows 11 Pro is ready to work within seconds of pressing the power button. It is a natural fit for reception desks, back-office workstations, point-of-sale terminals and student study setups.

The 16GB of DDR4 memory gives you real headroom. You can keep a dozen browser tabs open alongside a spreadsheet, a video conference and your email client without the system slowing to a crawl. With integrated Intel UHD 630 graphics and DisplayPort output, adding a second monitor is straightforward — a simple upgrade that makes multitasking far more comfortable.

Because it draws so little power and runs quietly, the ProDesk 400 G5 Mini is well suited to always-on roles such as digital signage, thin-client access or a tidy home-office PC. It is not built for heavy gaming, 4K video editing or 3D rendering — but for the everyday tasks most people and businesses actually do, it delivers dependable performance in a footprint you will barely notice.
