8-GPU barebone, OneChassis 7U, PCIe 5.0, DDR5, AMD (retail RTX 5090)

$5,285 — no GPUs, 8 slots (10 dual-slot), PCIe 5.0 · no CPUs (2× SP5, EPYC 9004/9005) · no memory (24× DDR5) · 12× 3.5" bays, no drives · none (NIC risers; board 2× 1GbE). OneChassis 7U GPU chassis, PCIe 5.0 risers + TURIN2D24G-2L+. Lead time: 3-4 wk plus shipping from Shenzhen.

Specification

7U, dual-socket ASRock Rack tray, front and rear GPU trays (5× 4-slot or 10× dual-slot cards each; an 8-GPU build is 3 front + 5 rear), card limit 4 slots × 370 mm × 150 mm, 12× 3.5"/2.5" hot-swap bays, 5× 2000 W CRPS (4+1, 8 kW N+1), 4× 92 mm + 8× 80 mm hot-swap fans, 900 × 438 × 310 mm
ASRock Rack TURIN2D24G-2L+/500W (PCIe 5.0, 24× DDR5, EPYC 9004/9005 (SP5), 500 W CPUs)
No CPUs, memory, drives or GPUs: OneChassis sells chassis + risers + PSUs + motherboard only; the buyer fits CPUs and DIMMs locally (OneChassis holds no CPU stock)
PCIe cable risers tested twice (cable factory, then OneChassis on assembly); rails (2U full-extension, 85 kg) and 2 CPU coolers included
Takes retail 3.5-4-slot GeForce RTX 5090 cards (up to 8 as sold, 10 slots physically): the only listed host that does; every other 5090 line needs a custom passive card
