Best rig to run a 32B model for casual chat in Minnesota
At this usage, renting Claude Sonnet 4.6 beats owning for every rig that runs a 32B model. The least-bad build is the RTX 3090 (used), but that's a sovereignty call, not a savings one.
Same workload, same cloud, same electricity — we swap only the hardware and rank by real break-even. Rigs that can't run a 32B model are shown, never recommended. Compared against Claude Sonnet 4.6 ($3/M in, $15/M out); change the cloud in the lab.
