Dell OptiPlex 7040 MT review: specs, options & used prices

Hands-on-style overview of the Dell OptiPlex 7040 MT (Small Form Factor (SFF)): CPU, memory and storage configurations, used-market prices and upgrade notes. Typical configuration: Core i7-6700.

What this machine is

The Dell OptiPlex 7040 MT belongs to the class of machines that filled offices for years and now fills the secondary market โ€” 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.

Tracked used listings cluster around a median of $86 (4 active listings at the time of writing).

Configurations you will actually see

Configurations we track pair the OptiPlex 7040 MT with the Core i5-6500 and Core i7-6700. These are 6th-generation Intel Core parts. This generation predates official Windows 11 support, worth factoring in if a modern OS baseline matters to you.

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.

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: 45/100.

Who it fits

If the task is browsing, office documents, video calls, or a kiosk/POS role, the OptiPlex 7040 MT does the job at a low sensible price. It predates official Windows 11 support, which makes it a natural Linux or light-duty candidate โ€” a real factor if a modern OS baseline is required.

The spec sheet carries the full option ladder and tracked prices; for context, browse the desktop catalog or the Dell desktops page.

Verdict

The case for the OptiPlex 7040 MT 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 โ€” RAM and storage vary widely between listings. Tracked prices span $55 to $140, and most of that spread is configuration, not condition.

Our composite LB Score currently sits at 13/100 โ€” a score that mostly reflects the platform age โ€” use it to compare like with like, not against modern hardware.
