Overview
Next to the SYS-421GE-TNRT, the SYS-521GE-TNRT adds two things its spec table makes plain: slots for a pair of quad-width or triple-width accelerators, and a liquid-cooled processor option with a higher CPU power ceiling. H100 NVL and H200 NVL sit on its supported list alongside L40S and RTX PRO 6000 Blackwell Server Edition, all on a PCIe 5.0 dual-root switch over 4th or 5th Gen Xeon Scalable. This rack system is aimed at fine-tuning and large-model inference on PCIe cards, for teams not ready to commit to an HGX baseboard. Supplied new and configured to order: our buyers source the parts in China, and the Shenzhen team builds and cross-checks the system before release — powered on and booted on our bench, configuration checked against the spec, completeness and visual inspection, photos, logs and serials recorded. Our part is 1-yr hardwaresys RTB + vendor’s own warranty. Tell us whether you want H200 NVL in NVLink-bridged pairs or unbridged L40S cards, since that sets the slot order, 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.
