Well, my local AI addiction officially got out of hand tonight.

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?…
