Purpose-built SFF workstation

The Lenovo ThinkCentre Neo 55s is a small form factor desktop built for professional workloads. It pairs a six-core AMD Ryzen 5 220 processor with 64GB of DDR5 memory and a 2TB solid-state drive. Windows 11 Pro is pre-installed for business-grade security and management.

Included peripherals and connectivity

A wired keyboard and mouse are supplied in the box along with a 64GB USB flash drive. Video outputs comprise one HDMI 2.1 port and one DisplayPort connector, supporting dual 4K displays at 60Hz. The front panel adds a USB-C port with 10Gbps data, power delivery and DisplayPort alt mode, plus four USB-A ports at 5Gbps.

Verify your environment before purchase

The chassis measures 10.83 by 3.5 by 13.24 inches and weighs 9.55 pounds, so confirm desk or mount clearance. The internal power supply is rated at 200W, which limits future graphics card upgrades. Memory uses DDR5 SODIMM modules; the board is populated with two 32GB sticks, leaving no free slots for expansion without replacement.

Questions about this item

Will the 64 GB DDR5 memory need to be replaced or expanded later?

The system ships with 64 GB DDR5 4800 configured as two 32 GB modules, filling both SODIMM slots, so any future increase would require replacing the existing sticks rather than adding to them.

What limits sustained performance first during long workloads?

The 200 W power supply caps total system draw, so under continuous heavy load the CPU will hit its power ceiling before thermal throttling becomes the primary constraint.

How much fan noise and heat should I expect when the PC runs all day?

Air cooling in the 10.83 x 3.5 x 13.24 inch SFF chassis keeps the Ryzen 5 220 and Radeon graphics at safe temperatures with low acoustic output during typical business use.
