Lenovo ThinkCentre M73 · Intel Core i3 (4th Gen) · 8 GB / 500 GB HDD

Need a computer that stays put and just works? This Lenovo ThinkCentre M73 is exactly that. The ThinkCentre M-series is Lenovo's business desktop — the grey box you've probably seen under a desk in a bank branch or government office. Unexciting to look at, extremely dependable. The M73 is a compact office desktop; quiet, reliable and very affordable.

The Core i3 is a sensible, efficient chip for study, browsing, documents and video calls. This 4th-generation chip is older, but paired with an SSD it still handles documents, browsing, email and video calls comfortably. 8 GB RAM is the right amount for study, office work and normal multitasking. It comes with a 500 GB HDD, which gives you lots of room for files. For a much faster start-up, ask us to swap in an SSD before dispatch.

Build and everyday use

Compact tower or small-form-factor case with easy tool-less access inside. Connect your own monitor, keyboard and mouse. Plenty of USB ports for printers and scanners. It runs Windows 10 Pro. One honest note: Microsoft ended free security updates for Windows 10 in October 2025, so this is best for offline or office-network use, or enrol it in Microsoft's paid Extended Security Updates. Ask us if you'd prefer a Windows 11 option.
