Lenovo ThinkCentre M70s review: specs, options & used prices

What this machine is

As used-market small form factors go, the Lenovo ThinkCentre M70s (2020) is a known quantity: standard parts, a wide configuration ladder, and steady supply on the secondary market.

Business-line machines are the backbone of the secondary PC market for a practical reason: they were sold in large volumes to offices, serviced professionally, and then retired in bulk.

Across 5 tracked listings, the median asking price is $180.

Configurations you will actually see

Configurations we track pair the ThinkCentre M70s with the Core i5-10400. These are 10th-generation Intel Core parts. From the 8th generation on, these generally meet Windows 11 requirements.

Memory options run from 8 GB to 16 GB (8 GB, 16 GB). 8 GB is workable for one person; 16 GB is the comfortable setting for typical office and home use.

Solid-state storage options include 500GB SSD.

Upgrade path and running costs

The compact chassis accepts standard low-profile parts, and drive bays are typically accessible without tools. The trade-off is a small, often proprietary power supply — check it before planning any graphics add-on.

Our compactness rating for this chassis: 75/100 — compact by design.

Who it fits

If the task is browsing, office documents, video calls, or a kiosk/POS role, the ThinkCentre M70s does the job at a low sensible price.

Full specifications, current options and tracked prices live on its spec sheet; the desktop catalog and the Lenovo desktops page help place it among the alternatives.

Verdict

The case for the ThinkCentre M70s is simple: standard parts, predictable supply, and a price that leaves room in the budget for upgrades.

Buy it when you need a cheap, repairable machine for its class of work, and verify the configuration before paying — RAM and storage vary widely between listings. Tracked prices span $135 to $330, and most of that spread is configuration, not condition.

Our composite LB Score currently sits at 16/100 — a score that mostly reflects the platform age — use it to compare like with like, not against modern hardware.
