Local LLM builder: ~$600 buys a 6-GPU Gen4 backplane for multi-GPU expansion
TheZachMueller · x · 2026-10-11
In a hardware discussion about local LLM builds, TheZachMueller points honx to the closest fit: a 6-GPU Gen4 backplane at roughly $600 (no Gen5 version exists). The conversation explores reusing an existing 9950X3D + 256GB UDIMM platform with 2× RTX Pro 6000 and a 200G NIC, and how to get more Gen5 slots without an expensive CPU/RAM upgrade.
