Dell Precision 3620 Tower review: specs, options & used prices

What this machine is

As used-market workstation desktops go, the Dell Precision 3620 Tower is a known quantity: standard parts, a wide configuration ladder, and steady supply on the secondary market.

Workstation lines exist for sustained professional loads: server-derived CPU options, high memory ceilings, and a chassis designed to run all day rather than all morning.

Tracked used listings cluster around a median of $130 (15 active listings at the time of writing).

Configurations you will actually see

Configurations we track pair the Precision 3620 Tower with the Core i5-6500, Core i7-6700, Core i7-7700 and 4 more. Intel Core options span the 6th to 7th generations. This generation predates official Windows 11 support, worth factoring in if a modern OS baseline matters to you.

Memory options run from 4 GB to 32 GB (4 GB, 8 GB, 16 GB, 32 GB). For a current operating system, treat anything below 8 GB as a first upgrade, not a final configuration.

Solid-state storage options include 128GB SSD, 250GB SSD, 256GB SSD, 512GB NVMe and 512GB SSD.

Hard-disk listings (1TB HDD) also exist — an SSD remains the single most noticeable upgrade on this class of machine.

Drive options without a clear type in the listing (1TB SATA) should be verified with the seller.

Workstation notes

Workstation configurations target engineering, CAD, rendering and virtualisation workloads that run for hours, not minutes.

Expect higher idle draw and more fan noise than office small-form-factor machines; these were designed to be worked, not to whisper.

Who it fits

It fits engineering, CAD, rendering and pro-workstation roles on a budget — as long as the software tolerates the age of the platform. 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.

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

Verdict

The Precision 3620 Tower is not exciting, and that is the point: a known quantity with a known configuration ladder.

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 $57 to $250, and most of that spread is configuration, not condition.

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