Overview

The HP ProDesk 400 G3 Mini is a renewed micro-form-factor desktop designed for office environments where desk space is at a premium. Powered by an Intel Core i5-7500T quad-core processor running at 2.70GHz with turbo up to 3.30GHz, and paired with 8GB of DDR4 memory, it handles everyday productivity tasks — document editing, email, web applications, and video conferencing — with reliable responsiveness. The brand new 256GB SSD ensures fast boot times and quick application launches, a meaningful upgrade over the spinning hard drives found in many refurbished systems at this price point.

Connectivity is a strong suit for such a small machine. Six USB 3.0 ports and a USB Type-C port accommodate a wide range of peripherals, while dual DisplayPort outputs (plus HDMI via an included adapter) support multi-monitor setups. Built-in Intel Wi-Fi AC1200 and Bluetooth mean you won't sacrifice USB ports for wireless adapters. The package includes a wireless keyboard and mouse combo, power cord, and mouse pad, so setup is essentially plug-and-play. Running Windows 10 Pro, the ProDesk 400 G3 Mini is well-suited for small business deployments, reception desks, point-of-sale stations, or home office setups where reliable performance and a minimal footprint matter more than cutting-edge specs.
