Overview
For an inference or rendering farm built on L40S or RTX 6000 Ada cards over Sapphire Rapids or Emerald Rapids, this is the conventional answer: a dual-socket rack GPU server with a PCIe 5.0 dual-root switch and a full row of double-width slots. The SYS-421GE-TNRT is also unusual in listing Intel Xe Link bridges next to NVLink, and it carries ten-gigabit copper on the board, so a small cluster can come up before any fabric card is fitted. The unit is new. We assemble it to order from components bought through our China channel, and the Shenzhen warehouse signs it off: powered on and booted on our bench, configuration checked against the spec, completeness and visual inspection, photos, logs and serials recorded. Warranty reads 1-yr hardwaresys RTB + vendor’s own warranty. Settle the memory layout before ordering — one module per channel for speed, or two per channel for capacity at a lower clock — name the card model for the slots, and request a quote with both noted.

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.
