What are refurbished servers?

Refurbished servers are used business servers that we prepare for production use again. They often come from the data centres and server rooms of organisations that are renewing their infrastructure. You get proven hardware from well-known brands at a lower price than new.

And because no new server has to be manufactured, it is also a sustainable choice.

Benefits of refurbished servers

Better value than new

You pay less than for the same model new. Use the budget you save for extra memory, storage or a second node for redundancy.

Sustainable business

A large share of a server’s climate impact is created during manufacturing. The world generated 62 million tonnes of electronic waste in 2022, of which only 22.3% was documented as recycled (Global E-waste Monitor 2024). Every server that lasts longer helps to shrink that mountain.

Expand with the same model

Want to expand an existing cluster or replace a server with exactly the same model? Servers the manufacturer no longer sells are often still available refurbished. That keeps your environment consistent and easy to manage.

How a server gets a second life

Purchasing and registration

Purchasing and registration

We buy servers from organisations that are renewing their infrastructure. We register every server by serial number, so every step remains traceable.

Certified data erasure

Certified data erasure

We wipe all storage media with Blancco software. Drives that cannot be wiped are destroyed. Read more about data erasure.

Testing and repair

Testing and repair

We test processors, memory, power supplies, fans and controllers for function and stability. Parts that do not meet our standards are replaced.

Grading

Grading

Every server receives an A, B or C grade, which reflects its cosmetic condition, such as scratches or signs of use.

Configured to order

Configured to order

We assemble processor, memory, drives, RAID controller and network cards to suit your application and install the latest firmware on request.

Delivery and installation

Delivery and installation

Your server arrives ready to use. Need help? We also provide rack and stack, installation, migration and remote hands.

Our refurbished servers

From a single server for the office to a complete data centre environment: we supply refurbished server hardware for every application.

  • Rack servers: the standard in server rooms and data centres, in 1U, 2U and larger form factors. Strong for virtualisation with VMware, Hyper-V or Proxmox, for example.
  • Tower servers: a compact solution for offices without a server rack, for example as a file server or backup server.
  • Blade servers: plenty of computing power in a small space, ideal if you want to expand a chassis with extra blades.
  • GPU servers: for AI, machine learning and other compute-intensive tasks, for example with NVIDIA.

Refurbished or new: which suits your environment?

Both options have their place. This comparison helps you choose.

Refurbished server New server
Purchase price Lower than new for the same model Full list price
Older models Including models no longer sold new, useful for adding to a cluster Current product line only
Latest technology Proven models from one or more generations back The newest processor generation and usually more performance per watt
Warranty and support Lifetime warranty from Circular IT group, manufacturer support depending on model and licence Manufacturer warranty and support contract
Environmental impact Existing hardware lasts longer, no new manufacturing needed New raw materials and manufacturing needed

Many organisations combine both, for example new servers for the heaviest workloads and reconditioned servers for virtualisation, backup and test environments.

Frequently Asked Questions

  • Are refurbished servers reliable?

    Yes. Business servers are built to run day and night for years. Before a server leaves us, it has been tested and weak components have been replaced. If anything does not work as it should, it is covered by the warranty.

  • What is the difference between a refurbished and a second hand server?

    A second hand server is usually sold as it is, without checks and sometimes with the previous owner’s data still on the drives. A refurbished server has been wiped, tested and graded, and it comes with a warranty. So you know exactly what you are getting.

  • What warranty do I get on a refurbished server?

    Every server we refurbish comes with a lifetime warranty. You will find the terms for your model in your quotation.

  • Will I still receive firmware and security updates?

    For servers placed on the EU market since March 2021, manufacturers must keep the latest firmware available for at least eight years after the last unit of a model was placed on the market. On request, we install the most recent version before delivery.

  • Can I try a server first?

    Yes. Start with a Proof of Concept in your own environment, or rent the server first. After the rental period, you can often still take over the equipment.
