Compact business desktop with 64GB DDR5

The Lenovo ThinkCentre Neo 55s is a small-form-factor PC built for office and professional workloads. It pairs a 6-core AMD Ryzen 5 220 processor with 64GB of DDR5 memory and a 1TB SSD. Windows 11 Pro is pre-installed and a wired keyboard and mouse are included in the box.

Suits users who need high memory capacity

This system works well for multitasking, virtual machines and large datasets thanks to its 64GB DDR5 configuration. Buyers who require a discrete graphics card for 3D rendering or GPU compute workloads should look at a workstation with dedicated GPU support instead.

64GB DDR5 memory capacity decides fit

The machine ships with two 32GB DDR5 modules running at 4800MT/s, filling both SODIMM slots. If your workflow demands more than 64GB of RAM, this platform cannot be expanded further and a different system will be required.

Questions about this item

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

The SFF case measures 10.83 inches deep, 3.5 inches wide and 13.24 inches high, so check your shelf clearance against those exact dimensions.

How do I add the second 32 GB DDR5 module and which slot do I use first?

Install the first module in the primary DIMM slot, then add the second in the matching channel slot; the system ships with both 32 GB sticks already seated.

When should I replace the 200 W power supply if the fan gets noisy?

A 200 W unit in an SFF build typically runs 3 to 5 years before bearing wear becomes audible; swap it when noise appears or voltages drift.
