Pooling $8K for a shared local LLM rig takes 3.3 years to beat a $20/mo ChatGPT sub
Any-Blacksmith-2054 · reddit · 2026-10-30
A Redditor ran the napkin math on neighbors pooling money for a shared local AI rig: a single-GPU 70B-class box costs $3–5K, a multi-user setup with 2–4 cards runs $6–10K, and 24/7 power draw of 300–600W stings at EU electricity prices. Splitting an $8K rig across 10 households means $800 each and a 3.3-year payback vs $240/yr subscriptions — assuming free electricity and maintenance. His verdict: it's not a financial win; the real value is LAN-only privacy, no rate limits, uncensored/custom models and hobby fun. He asks whether anyone has actually run a shared rig, what the sweet-spot config for 5–10 concurrent users looks like, and how badly EU power prices kill the idea.
