Overview
The ThinkCentre M75q (Tiny) is one of the great refurb deals in 2026. €150–250 buys a 2021-era Ryzen 5 with 16 GB RAM, an NVMe slot, USB 3.0+ — comfortably running Hermes Agent with browser tool. Local LLM ceiling is real (Mistral 7B Q4 around 8-10 tok/s) but the price/performance is unbeatable for new self-hosters. Watch the seller for genuine refurb units versus “tested working” ones with worn fans.
Best for
- Budget self-hosters wanting more than a Pi 5 can offer
- Cost-optimised always-on agent hosting
- Refurb-friendly builders
Not for
- Local LLM beyond 7B Q4 (modest GPU)
- Brand-new-hardware purists
- Specific compliance requirements (used hardware introduces audit gaps)
Compatible self-hosted agents
