Compact business desktop

The Lenovo ThinkCentre M75s Gen 1 is a tiny form-factor PC built for office and mainstream workloads. It ships with Windows 11 Pro and an AMD Ryzen 5 PRO 3400GE processor paired with integrated AMD Radeon Vega 11 graphics. The system includes 16GB DDR4 memory and a 256GB NVMe SSD. It suits buyers who need a space-saving, ready-to-deploy machine.

Simple drop-in deployment

Because the unit arrives fully assembled with an operating system installed, installation consists of connecting power, display cables and peripherals. The tiny chassis limits internal upgrades, so adding a discrete graphics card or extra internal storage bays is not practical. Buyers who want more storage or a second card must rely on external solutions.

256GB NVMe boot drive

The single 256GB NVMe solid-state drive holds the operating system and core applications, delivering fast start-up and load times. Capacity is fixed at 256GB, so users with large local data sets will need supplementary external or network storage. No other storage media are included.

Questions about this item

How can I confirm the AMD Radeon Vega 11 graphics are active after installing drivers?

Open Device Manager and verify AMD Radeon Vega 11 appears under Display adapters, then run a quick DirectX diagnostic to see the GPU name and driver version.

Which cables and accessories are included with the ThinkCentre M75s Gen 1 and what must I purchase separately?

The unit ships with a power cord and internal components only; you need to supply DisplayPort cables, keyboard, mouse and any USB peripherals.

Should I choose the 16 GB DDR4 configuration or look for a higher-capacity option for the Ryzen 5 PRO 3400GE?

The listed model comes with 16 GB DDR4 soldered; if you need more memory, confirm the board supports additional SO-DIMM slots before buying.
