A Business Desktop Built for the Office, Not the Showroom
The Lenovo ThinkCentre M720S is a Small Form Factor (SFF) desktop from Lenovo's business ThinkCentre line, launched alongside the 8th Gen Intel Core "Coffee Lake" platform and later offered with 9th Gen options. It sits between Lenovo's ultra-compact Tiny (M720Q/M900 Tiny) PCs and full-size towers — a case roughly one-third the volume of a standard ATX tower, but still large enough for a 3.5" hard drive bay and a low-profile expansion slot. This refurbished unit has been pulled from corporate fleets, tested end-to-end, and is sold by Serverwale with a working warranty — ideal for buyers who want dependable business hardware without new-PC pricing.
Processor and Chipset
The M720S was built around Intel's B360 chipset paired with 8th and 9th Gen Intel Core processors on the LGA1151 socket — configurations spanning Celeron and Pentium Gold entry chips up to Core i3, i5, and i7 (e.g. i3-8100, i5-8400/8500, i7-8700). Because the platform uses the B360 chipset rather than Q370, these units do not carry Intel vPro remote-management — a detail worth knowing if you're comparing this to Lenovo's Q370-based M920 series. For everyday office computing, browsing, accounting software, and multi-window multitasking, the i5/i7 configurations on this platform still hold up well years on.
Memory and Storage
The M720S takes DDR4 UDIMM memory at up to 2666MHz across four dual-channel slots, officially supported up to 64GB (4x16GB) — comfortably enough for virtualisation, heavier spreadsheets, or several browser-and-office-suite windows running at once. On the storage side, the SFF chassis includes an internal M.2 slot for a SATA or NVMe SSD plus a dedicated 3.5" bay (with an optional 2.5" bracket), so it's straightforward to run a fast boot SSD alongside a larger HDD for bulk storage — a configuration this chassis was specifically designed to support, unlike Lenovo's Tiny-format machines.
Expansion, Graphics and Build
Being an SFF chassis, expansion is deliberately compact: one low-profile PCIe 3.0 x16 slot plus two low-profile PCIe 3.0 x1 slots. The x16 slot can accept a low-profile discrete graphics card if your workload needs one, though it's not designed for full-height gaming GPUs. Out of the box the platform runs on integrated Intel UHD Graphics 630, which is more than adequate for office, dual-monitor, and light design work. Internal power is handled by a compact SFF-format PSU (Lenovo offered 180W/210W/260W variants), and the chassis includes a TPM 2.0 security chip standard on ThinkCentre business desktops.
Condition, Testing and Warranty
Every M720S sold by Serverwale is inspected, stress-tested, and cleaned before listing — CPU, RAM, storage, ports and Wi-Fi (where fitted) are all verified working. Units ship with a licensed Windows 10 Pro installation and a Serverwale warranty for peace of mind. If you need a reliable, quiet, desk-friendly business PC for an office, school lab, or home workstation without new-hardware pricing, the M720S is a solid, honestly-specced choice.
