Lenovo M900 Tower desktop

The Lenovo M900 Tower is a business desktop computer running Windows 11 Pro. It is aimed at office workers and home users who need a reliable system for daily productivity tasks. The tower form factor fits standard workspaces and supports general multitasking workloads. It is not suited for buyers who require high-end graphics performance or extensive internal expansion.

16 GB DDR4 memory and 256 GB SSD

The system includes 16 GB of DDR4 memory, which provides comfortable headroom for multiple browser tabs, office suites and background services. The 256 GB solid-state drive offers fast boot and application launch times for the operating system and core programs. Storage runs out quickly for users who keep large media libraries, project archives or modern game installations on the primary drive.

Radeon RX 550 graphics with RGB keyboard and mouse

An AMD Radeon RX 550 graphics card handles desktop composition, video playback and light creative work. It allows smooth streaming and older esports titles at modest settings. The bundled RGB keyboard and mouse add immediate input convenience and adjustable backlighting for low-light environments. No monitor is included, so buyers without an existing display must purchase one separately.

Questions about this item

Will the Radeon 550 graphics card run alongside my older PCIe 2.0 motherboard if I move it to another system?

The Radeon 550 uses a standard PCI Express interface and is backward compatible with PCIe 2.0 slots, though it will operate at the lower bandwidth of that generation.

How can I verify the 16 GB DDR4 memory is running at its rated speed after installation?

Open Task Manager, select the Performance tab, click Memory and confirm the speed shown matches the module rating; you can also check the BIOS memory information screen.

Does the box include a Wi-Fi antenna or must I purchase one separately?

The system includes the internal Wi-Fi card; the external screw-on antennas are supplied in the accessory box, so no separate purchase is needed.
