Business SFF Desktop

The Lenovo ThinkCentre Neo 55s is a small-form-factor desktop built for office and home-workstation use. It ships with Windows 11 Pro, a wired keyboard and mouse, and integrated AMD Radeon graphics that can drive two 4K monitors. The black chassis uses air cooling and fits on a crowded desk.

Upgrade from older SFF PCs

Replacing a tower or an earlier SFF unit with this model adds a 6-core AMD Ryzen 5 220 processor that reaches 4.9 GHz and 32 GB of DDR5-4800 memory in a 16 GB × 2 configuration. The jump is worthwhile when daily workloads involve many browser tabs, large spreadsheets or simultaneous business applications that exceed 8 GB or 16 GB of RAM.

Check power and ports before ordering

The internal power supply is rated at 200 W, so verify that any planned add-in cards stay within that budget. Front and rear I/O include four USB-A 5 Gbps ports, one USB-C 10 Gbps port with power delivery and DisplayPort alt-mode, HDMI 2.1, DisplayPort, Ethernet and a headset jack. Ensure your monitors and peripherals match these connections.

Questions about this item

Will the 10.83 x 3.5 x 13.24 inch chassis fit on my desk shelf?

The small-form-factor case measures 10.83 inches deep, 3.5 inches wide and 13.24 inches high, so it fits on most standard shelves.

What is the correct order for connecting the HDMI 2.1 and DisplayPort cables during first boot?

Connect the monitor to either the HDMI 2.1 or DisplayPort output, power on the PC, then let Windows 11 Pro detect the display automatically.

When should I plan to replace the 200 W power supply?

The 200 W unit is rated for continuous office workloads; replace it only if you add components that exceed its capacity or if it shows voltage instability.
