2U Rackmount Server Barebone

This 2U rackmount server barebone provides a chassis with integrated power and remote management for custom deployments. It is built for IT teams assembling a single-socket AMD platform in a standard rack environment. The unit includes a redundant 1200W CRPS power supply rated 80-PLUS Platinum and IPMI for out-of-band control.

Suited for single-socket AMD EPYC 4004

This barebone fits administrators who need a compact 2U form factor with redundant platinum power and IPMI. It is not suited for workloads requiring dual-socket scale, more than four memory channels, or additional full-height PCIe 5.0 x16 slots beyond the one provided.

One PCIe 5.0 x16 full-height full-length slot

The expansion layout centres on a single FHFL PCIe 5.0 x16 slot paired with one FHHL PCIe 4.0 x4 slot and two M.2 positions. Network connectivity is limited to dual 1GbE RJ45 ports via Intel i210. Verify that your accelerator, storage or networking cards match this slot count and generation before purchase.
