Buying used servers: what really matters
Generation, form factor, CPU, memory, controller, remote management and warranty: the points that decide whether a used server fits your workload.

Servers
Used servers from Dell, HPE, Lenovo and Supermicro deliver data center performance at a fraction of the original price. This category covers rack servers, tower servers, GPU servers and storage servers, which we configure to your specification with processors, memory, drives, RAID controller and network cards. Before shipping, every system is cleaned, BIOS and management controller are updated, and the machine is checked and tested. Warranty is 12 to 36 months depending on the item. When choosing, check the platform generation (for example Dell 14G with Xeon Scalable or HPE Gen10), the number and size of drive bays and the free PCIe slots for later upgrades. We sell to businesses and private customers; approved businesses can buy on invoice.

Buying used servers: form factor, generation and specification
Used servers from the data centre are often the more economical choice: enterprise hardware is built to run around the clock, yet it loses most of its value in the first few years. Whether a second-hand or a new server suits you better depends on workload, power costs and how long you plan to run it. The sections below help you choose form factor, platform generation and specification, and show how to recognise a properly refurbished machine.
Used or new: when buying second-hand pays off
A used server makes sense when you need lots of cores, memory or drive bays on a limited budget: virtualisation hosts running Proxmox or Hyper-V, test and development environments, backup targets, cluster nodes or a homelab. A dual-socket system with 40 cores and 256 GB of RAM often costs less second-hand than a new entry-level server with a fraction of that.
Buy new if you genuinely need the latest platform, such as PCIe 5.0 or DDR5, or if a vendor contract with on-site service is mandatory. Also check that your operating system or hypervisor officially supports the generation you pick; those support lists change with every release.
