About this collection

Explore refurbished server listings for business upgrades, lab environments and data-centre expansion. Compare Dell, HPE and other available manufacturers by model, generation and chassis configuration.

Check each listing for its stated condition and included components: a CTO chassis and a fully configured system are not the same. Contact KahnServers for help confirming a complete build.

Hardware supplied by KahnServers includes a 90-day warranty. Check current availability and the individual product specification before ordering.
