Three years of iterative development across five complete hardware revisions. CAD design, custom aluminum structure, 3D-printed components, internal network at tens of Gbps. Validated under sustained load for 12 hours with all GPUs at 100%. Passive hardware repurposed for continuous-load operation in a residential environment, with measured thermal, acoustic, and vibration specifications.
Highlights
- 4 generations of systems designed and built since 2023
- Thermal validation: 8 GPUs at 100% for 12h, 35-52°C range, zero drift
- Production: 32B-parameter model on 2 used GPUs (€300 total)
- In-house CAD design, custom aluminum, 3D-printed components
- Internal network at tens of Gbps
- Measured acoustic and vibration specifications
- Validate cheap, deploy expensive.
System in continuous operation. Technical lessons documented in dedicated articles.
