Overview
The OptiPlex 3070/5070 Micro is a 2019-vintage corporate refurb that hits the market at €100-180 in 2026. Intel i5 8th gen, 8-16 GB RAM, NVMe — enough to run Hermes Agent without browser tool, plenty for Nanobot. Local LLM is essentially out of scope (the iGPU is too slow). Power draw is meaningfully higher than modern mini PCs, eating into the cost advantage on always-on workloads. Worth it as the cheapest credible entry, not as a long-term deployment.
Best for
- Absolute budget self-hosting
- Always-on agent hosting where local LLM is irrelevant
- Educational / learning setups
Not for
- Local LLM (8th gen Intel iGPU is too slow)
- Browser automation at scale
- Anyone valuing low electricity bills (2019 efficiency)
Compatible self-hosted agents
