Local Ai Server Quad GPU Rig - 1 Year Review

One year in with my Quad 3090 Local AI rig is a great time for me to go over what I would change, alternatives that can dramatically lower costs, and what is working great in the system. Just finished writeup and the price on this variant vs the server variant is ~$1,300. This brings the cost per GB VRAM down by $13.65 which is pretty significant.
