Overview
The SR645 was Lenovo's first-wave AMD compact rack server, and the fleet that proved the concept is now rotating out — which makes refurbished units both plentiful and well understood. For virtualisation farms and web tiers, it remains a thoroughly modern machine. The generation is old enough to be cheap and recent enough to run current hypervisors without argument. Every unit is grade A, bought out of traceable decommissions in China and finished at our Shenzhen line: boot verification, configuration match, inspection, photo set, serial record. It ships under 1-yr hardwaresys RTB. Buyers standardising on the platform new will find that listing adjacent. State the cluster size you are building and request a quote.

Common problems when buying rack servers
"In stock" that isn't
We quote real availability — In Shenzhen — ready, or build-to-order with a date — never a stock status we can't hold.
Grey-market boxes with no history
Every unit is QC-tested with a documented report; you see the checks before it ships.
Refurb that's really e-waste
Grade A refurbished only, same one-year warranty as new — or we tell you to buy new instead.
