12 x 3.5-inch backplane capacity

This barebone server provides twelve 3.5-inch drive backplanes for high-density storage builds. The chassis arrives without CPU, memory, drives, expansion cards or power supplies. Integrators can populate every bay with the storage mix their workload demands.

Who this suits and who should look elsewhere

Organisations building custom storage nodes or backup targets benefit from the empty chassis and flexible processor choice. Buyers who need a complete, ready-to-run system with CPUs, memory or drives pre-installed should choose a configured model instead.

LGA 3647 socket compatibility

The motherboard uses an LGA 3647 socket, so only processors designed for that socket will fit. Confirm the exact CPU SKU before purchase because no processor is included and the socket type cannot be changed.

Questions about this item

What does the 12 x 3.5-inch backplane count mean for actual drive capacity?

The chassis accepts up to twelve 3.5-inch drives directly into the backplanes, giving you twelve hot-swap bays without extra cages or cables.

The CPU socket is listed as LGA 3647 — what does that dictate for cooler clearance and processor choice?

LGA 3647 is the physical socket on the board; you must select a compatible processor and a heatsink rated for that socket and the 2U height limit.

What mounting hardware is needed to install this barebone in a rack?

The unit is a rack-mount design; you will need sliding rails or fixed shelves that match the chassis depth and thread pattern.
