128 GB of unified memory in a mini PC. Holds gpt-oss-120b with room to spare; dense 70B models are slow.
Data checked: 2026-10-12. Review interval shown below. Prices need review after 30 days; specifications and benchmark collections after 90 days. Dates describe the recorded check, not a live retailer quote.
- Verified Checked against the primary source (for example the model’s config.json on Hugging Face).
- Sourced Taken from a cited source; not yet independently checked.
- Estimate Calculated with the published formulas; not a measurement.
- Sample Placeholder data for layout; not a real figure.
- Not yet measured No public, citable score found for this benchmark yet. We never fill the gap with a guess.
Verified metadata is not a measured performance result. Only cited runs matching model, device, quant and recorded context can replace speed estimates. Estimates assume one stream and F16 KV cache, with a ±25% uncertainty band. A published run applies only to its recorded runtime and conditions; missing settings are unknown.
Evidence labels · Freshness policy · Calculation methodology
Includes the listed system parts. Excludes tax, shipping, peripherals, maintenance, financing and resale. Sample parts prices may differ from current hardware catalogue prices. Electricity assumes 120 W whole-system load for 4 h and 15 W idle for 20 h daily, 30 days at $0.15/kWh. Power is unmeasured.
Parts list
Price from CFG (Oct 2026); 120 W load is the brief's break-even assumption.

Break-even = hardware ÷ (plan − electricity). It ignores capability: a local model is not a frontier model. Adjust the numbers.
