Lenovo ThinkCentre M73 SFF Core i5 4570 3.2GHz 8GB DDR3 480GB SSD

Compact desktop for office tasks

The Lenovo ThinkCentre M73 SFF is a small-form-factor desktop built around an Intel Core i5 4570 running at 3.2 GHz with a turbo up to 3.6 GHz. It ships with 8 GB of DDR3 memory and a 480 GB SSD, providing responsive performance for everyday business applications. Windows 10 Pro 64-bit is pre-installed, and a Wi-Fi adapter plus a gaming keyboard and mouse are included. The integrated Intel HD Graphics 4600 handles standard display output without a discrete card.

Black SFF chassis with USB 3.0

The black Slim Form Factor case fits tight spaces and uses an Intel motherboard with two DDR3 DIMM slots supporting up to 16 GB total at 1600 MHz. USB 3.0 ports move data up to 10 times faster than older USB while remaining backward-compatible. Wired Ethernet is onboard, and the supplied Wi-Fi adapter adds wireless connectivity. No optical drive or monitor is included, keeping the footprint minimal for desk or VESA mounting.

Upgrade from older hard-drive PCs

Replacing a traditional hard-drive system with this SSD-equipped unit cuts boot and load times dramatically for general office work, web browsing and light multitasking. The 4th-generation Core i5 and 8 GB DDR3 cover typical productivity needs, while the two memory slots allow expansion to 16 GB if workloads grow. Buyers who need discrete graphics, more than 16 GB RAM or newer CPU instruction sets should look at larger or newer platforms.
