Lenovo ThinkCentre M91p · Intel Core i5 (2nd Gen) · 8 GB / 500 GB HDD

A good desktop is still the most cost-effective way to get a reliable computer on a desk, and this Lenovo ThinkCentre M91p proves it. 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 M91p is an older business desktop, fine for billing, typing and simple counter jobs.

The Core i5 is the sweet spot for most people — quick enough for multitasking, Office, coding and online classes, without the extra cost of an i7. It's an older 2nd-generation chip, so think of this as a dependable machine for billing software, documents, browsing and school work rather than heavy multitasking. 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.
