Overview
Single-socket compute with cloud-fleet habits: one 4th or 5th Gen Xeon Scalable, memory that can run two modules per channel when capacity matters more than speed, an AIOM slot for networking and room for a pair of double-width GPUs. The SYS-521C-NR suits service providers and SaaS operators who want uniform rack nodes that hold both drives and a card or two, at the licensing cost of one socket. NVMe and SATA both appear in its table, each with RAID, on the Intel C741 chipset. Supplied new. We buy the parts to your build sheet through suppliers across China, and the Shenzhen team completes the system, verifies it and records serial numbers before it goes out. Cover runs 1-yr hardwaresys RTB + vendor’s own warranty. The AIOM slot has no default card, so name the network adapter you want — speed, media and number of links — 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.
