The Dell Precision 3660 Tower is a small-form-factor workstation Dell sold across 2022 and 2023, built for engineers, architects, and data scientists who need certified professional graphics without the footprint of a full-size tower. It pairs 12th and 13th Gen Intel Core desktop chips with NVIDIA's RTX A-series workstation GPUs, making it a common pick for CAD, simulation, and rendering workloads that outgrow a standard business desktop. Because it ships with ISV-certified drivers and a tool-less chassis built for easy component swaps, the 3660 tends to hold its value longer than consumer towers of the same age, especially in higher CPU and GPU tiers. Pick your processor, graphics card, and condition in the configuration tool above for an instant cash offer. If you want the mechanics of a trade-in before you commit, you can see how the process works, and if this isn't your only Dell on hand, you can sell your Dell laptop alongside it.

Confirm you have the Dell Precision 3660 Tower

The fastest way to confirm your exact build is through Windows itself. Press Windows key + R, type msinfo32, and press Enter. The System Model field will read "Precision 3660 Tower," and the same window lists your installed processor and RAM. Running dxdiag instead gives you a quicker snapshot of the CPU and graphics card if that's all you need to check.

Windows System Information

  • Windows key + R, type msinfo32, press Enter
  • System Model confirms "Precision 3660 Tower"
  • Processor and installed RAM listed on the same screen

Dell Service Tag

  • Pull-out tag on the front or top of the chassis, or a sticker on the rear panel
  • Enter the tag at Dell's support site for the full original build sheet
  • Also visible in BIOS setup on startup

Prefer a visual check? The 3660 is a compact vertical tower with a tool-less side panel that pops off without screws, a front panel cluster of USB-A and USB-C ports, and a visible "Precision" badge on the front bezel. If you need help matching a physical unit to a model number, Dell's own lookup guide walks through it step by step.

Core hardware configurations

Processor

  • Intel Core i5, i7, or i9, 12th Gen or 13th Gen desktop silicon
  • LGA1700 socket, no soldered CPU
  • Higher core-count i9 configurations command the strongest resale demand for CPU-bound workloads

Graphics

  • NVIDIA RTX A4500, RTX A5000, or RTX A6000 workstation GPU, or an "Other" listed alternative
  • ISV-certified drivers for CAD and simulation software
  • Graphics tier moves resale value more than any other single spec — an RTX A6000 build is worth substantially more than an A4500 build in otherwise identical condition

Memory

  • DDR5 memory across multiple DIMM slots
  • User-upgradable, not soldered to the board
  • A fully populated, higher-capacity build sells for more than a minimum-RAM unit

Storage

  • M.2 PCIe NVMe slot for the primary drive
  • Additional 2.5" or 3.5" SATA bays for secondary storage
  • Both upgradable after purchase

Display & audio

Display support: As a tower, the 3660 has no built-in screen. Monitor output runs through the installed RTX card's DisplayPort connectors, so the number of simultaneous displays you can drive depends on which GPU tier is installed.

Audio: Onboard Realtek audio codec with a front-panel headphone/microphone combo jack and rear line-out. There is no discrete speaker system; audio output relies on connected headphones or external speakers.

Ports & connectivity

Port selection is split between a front cluster meant for daily plug-in use and a rear cluster for permanent cabling.

Front panel
  • USB-C
  • USB-A (multiple)
  • Headphone/microphone combo jack
Rear panel
  • USB 3.2 Type-A ports
  • Gigabit Ethernet (RJ45)
  • DisplayPort outputs from the installed GPU
  • Line-out audio

Battery, build & more

Power supply: Internal PSU sized to the installed GPU. A unit configured with an RTX A6000 draws considerably more power than one with an RTX A4500, so PSU wattage varies by build.

Chassis & build: Compact vertical tower with a tool-less side panel and quick-release brackets for the GPU and drive bays, designed for fast servicing without a screwdriver.

Software: Ships with Windows, with select configurations also offered under Dell's Linux-certified program for workstation ISVs. Dell Precision Optimizer is typically preloaded to tune performance per application.

Market positioning: Sits in the professional workstation tier rather than the consumer desktop tier. Buyers shopping this model already know they want certified graphics, so complete, well-specced configurations move faster than stripped-down base builds.

Frequently asked questions

01 How do I find the model number or exact configuration?
Open Windows System Information by pressing Windows key + R, typing msinfo32, and pressing Enter. The System Model field will confirm "Precision 3660 Tower," and the same screen lists your installed processor and total RAM. For the GPU, check Device Manager under Display adapters, or open dxdiag for a quick summary. The Dell Service Tag, found on a pull-out tag on the chassis or in BIOS setup, gives you the complete original build sheet from Dell's own support site if you want to double-check everything at once.
02 How do I tell it apart from the Precision 3260 Compact?
Check the chassis shape and the System Model field first. The 3660 is a vertical small-form-factor tower with room for full-height workstation GPUs, while the Precision 3260 Compact is a smaller, ultra-compact desktop with limited or no discrete GPU support. Running msinfo32 removes any guesswork, since the System Model line will read the exact name printed on your unit rather than a similar-sounding sibling.
03 Can I sell it with damage or if it won't turn on?
Yes, in most cases. A unit that won't power on, has a missing GPU, no operating system installed, or general cosmetic wear can still be quoted and sold, since the quote adjusts for condition rather than requiring a working machine. What matters more is account and security state: any BIOS administrator password must be removed, and if the drive was BitLocker-encrypted and tied to a Microsoft account, that device needs to be removed from the account before shipping. A locked-down system that can't be wiped is harder to place and will affect the offer.
04 What raises the trade-in value the most?
The installed GPU matters more than any other spec. An RTX A6000 build is worth meaningfully more than the same tower with an RTX A4500, since the graphics tier drives most of the professional demand for this machine. After that, higher-tier i7 or i9 processors, a fuller RAM configuration, and larger NVMe storage all help. Including the original power cable and any mounting brackets, and keeping the chassis free of dents or missing panels, also keeps the offer closer to the top of the range.
05 How do I erase it and remove my accounts, and how do I get paid?
Go to Settings → System → Recovery → Reset this PC and choose to remove everything. Before you reset, go to your Microsoft account online and remove this device from the list of registered devices, and if BitLocker was enabled, suspend it so the wipe completes cleanly. Once the reset finishes, the drive is clear of your data and accounts. From there, shipping to Gadget Salvation is free and insured, and payment goes out after inspection and testing, by PayPal, Venmo, Zelle, CashApp, or check. Full step-by-step guidance, including drive-specific notes, is on our data erasure protocols page.
