This is exactly the kind of chart that gets better the more suspicious it is of its own inputs. Since Gemini is extracting specs from listings, I would love to see a small confidence field or "last verified from listing" date next to each point.
Two fields that would make the Pareto view easier to trust:
1. New vs refurbished vs unknown. Mini PC listings blur that line constantly.
2. Power draw at idle and under load, even if it starts as a rough bucket. A box that wins on dollars can lose badly if it is going to sit in a homelab for three years.
The CPU/GPU/storage/memory toggle is nice. It makes the site feel like a tiny buying lab instead of another affiliate table.
