TL;DR: Get a refurbished Lenovo ThinkCentre M75q Gen 2 mini PC with Windows 11 Pro for $329.99 (reg. $749.99) during Deal Days.

Microsoft ended support for Windows 10 in October 2025, so a PC still running it no longer gets regular security updates. Replacing that machine doesn’t have to mean buying a big tower. For Deal Days, Popular Science’s version of Prime Day, a refurbished Lenovo ThinkCentre M75q Gen 2 mini PC is on sale for $329.99 (reg. $749.99), with Windows 11 Pro already installed.

Six cores in a case 1.4 inches tall

This refurbished unit has a Grade A rating. That means it arrives in near-mint condition, with little or no scuffing on the case. Lenovo fits a full desktop into a box measuring 7.2 by 7.1 by 1.4 inches and weighing 2.9 pounds, so it takes up almost no room next to your monitor.

Inside is an AMD Ryzen 5 PRO 5650GE processor with six cores and 12 threads. Clock speed ranges from 3.4 GHz to 4.4 GHz on boost. RAM is 16GB of DDR4, and the machine supports up to 32GB if you want to upgrade later. Storage is a 256GB NVMe SSD, so boot times and file access stay quick.

AMD Radeon Vega graphics can drive up to three monitors through the HDMI and DisplayPort outputs. You also get USB-C and USB 3.2 ports on the front and back, gigabit Ethernet, Wi-Fi, and Bluetooth 4.2.

A wired keyboard and mouse come in the box, so a monitor is the only thing you need to add. A third-party 90-day parts-and-labor warranty is included, too.

You can get a refurbished Lenovo ThinkCentre M75q Gen 2 on sale for $329.99 (reg. $749.99). No coupon is needed.
