Lenovo ThinkCentre M73 review: specs, options & used prices

What this machine is

The Lenovo ThinkCentre M73 belongs to the class of machines that filled offices for years and now fills the secondary market — practical, repairable, and priced accordingly.

Corporate fleets retire machines like this in batches, which is why the used supply is steady and prices stay predictable.

Across 3 tracked listings, the median asking price is $50.

Configurations you will actually see

The CPU options we track for the ThinkCentre M73 are the Core i5-4460T and Core i5-4570T. These are 4th-generation Intel Core parts. This generation predates official Windows 11 support, worth factoring in if a modern OS baseline matters to you. T-suffixed variants are the lower-wattage versions of the same chips: cooler and quieter, a little slower.

Memory options run from 4 GB to 8 GB (4 GB, 8 GB). For a current operating system, treat anything below 8 GB as a first upgrade, not a final configuration.

Solid-state storage options include 120GB SSD.

Hard-disk listings (455GB HDD) also exist — an SSD remains the single most noticeable upgrade on this class of machine.

Upgrade path and running costs

The full-size case leaves room for standard parts and a conventional power supply, which makes this one of the easiest classes of machine to upgrade and repair.

Our compactness rating for this chassis: 100/100 — the smallest class we rate.

Who it fits

If the task is browsing, office documents, video calls, or a kiosk/POS role, the ThinkCentre M73 does the job at a low sensible price. It predates official Windows 11 support, which makes it a natural Linux or light-duty candidate — a real factor if a modern OS baseline is required.

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 M73 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 $49 to $120, and most of that spread is configuration, not condition.

Our composite LB Score currently sits at 10/100 — a score that mostly reflects the platform age — use it to compare like with like, not against modern hardware.
