Refurbished ThinkCentre M720-SFF business desktop

The Lenovo ThinkCentre M720-SFF is a refurbished slim-form-factor desktop built around an Intel Core i7-8700 3.20 GHz 6-core processor with 12 MB L3 cache. It ships with 16 GB DDR4 memory, a 256 GB M.2 NVMe SSD, a DVD optical drive and Windows 11 Pro 64-bit. Integrated Intel UHD Graphics 630 drives up to three displays via VGA and two DisplayPort outputs.

Suits office users needing Windows 11 Pro

This configuration suits offices that require Windows 11 Pro out of the box, a small chassis that fits tight desk spaces and enough multi-thread performance for typical productivity workloads. Buyers who need discrete graphics for CAD or rendering, more than 16 GB RAM for heavy virtualisation, additional 2.5-inch drive bays or a standard ATX power supply should look at other form factors.

256 GB M.2 NVMe SSD capacity decides fit

The single specification that determines whether this unit meets the requirement is the 256 GB M.2 NVMe SSD. If the workload demands a larger primary drive or secondary mechanical storage, the existing capacity will be insufficient and the slim chassis limits internal expansion options.

Questions about this item

How do I add more DDR4 memory to the M720-SFF, and what step is often missed?

Open the chassis, insert the module into the empty DDR4 slot until the side clips click, then enter BIOS to confirm the new total is recognised.

Which component in this M720-SFF will need replacement first?

The 256 GB M.2 NVMe SSD has a finite write endurance; plan to replace it once the drive health tools report high wear.

What limit appears first when the i7-8700 runs at full load for long periods?

The small-form-factor cooler reaches its thermal capacity, causing the CPU to reduce its 3.20 GHz boost frequency.
