Overview

The Lenovo All-in-One Desktop consolidates a full PC into a clean 21.5-inch form factor, pairing a Full HD IPS anti-glare display with an 11th-generation Intel Core i3-1115G4 processor capable of turbo speeds up to 4.1 GHz. With configurable memory up to 32GB of DDR4 and storage up to a 2TB PCIe M.2 SSD, this machine can be equipped to handle anything from everyday document work and web browsing to media organization and light multitasking. The anti-glare panel's wide IPS viewing angles keep the screen readable from off-axis positions, a useful trait in shared desks or consultation settings.

Where this all-in-one stands out is its completeness: a built-in webcam is ready for video conferencing, a DVD-RW drive handles physical media without needing an external accessory, and a keyboard and mouse are included in the box. Connectivity covers the essentials with HDMI-out for adding a second display, two USB 3.2 Gen 2 ports, two USB 2.0 ports, Ethernet, Wi-Fi, and Bluetooth. Running Windows 11 Pro, the system suits small-business and home-office environments where a minimal-footprint, ready-to-go workstation is the priority. Its Raven Black finish keeps the aesthetic understated and professional.
