“Well, my local AI addiction officially got out of hand tonight.”
u/AnouarRifi’s local-AI hardware question, quoted in full. Photos from the same post.
Met a guy off Facebook Marketplace and scored 2x RTX 3090 Founders Editions for €1,700.
The problem? I already had one 3090 FE.
I am now sitting in my room looking at three 3090 FEs (72 GB GDDR6X VRAM), and my current case barely fits one card, and that was only after I literally took pliers and bent the inner metal bracket to shove it in. My motherboard is just a standard B760.
I clearly can't put three 3-slot cards in this PC. What is the cheapest, most sensible way forward to run all three (or two) for LLMs?
Open-air mining frame + PCIe 4.0 risers + dual PSU?
Get a giant full-tower case?
Just sell the 3rd card for €1,100, keep 48 GB VRAM, and fund a proper dual-GPU build?
Any chassis/frame or PSU recommendations for handling ~1,100W+ of 3090s would be appreciated.
