Five free tools for building or upgrading a gaming PC: a PSU calculator you can embed on your own site, a "will it fit?" checker for graphics cards and coolers, a CPU bottleneck test that reads the GPU usage you measure in your own game, a "can my PC run it?" check against official game requirements, and an open power table (CSV and JSON, CC BY 4.0). Every number links to the maker's spec page. No sign-up, in English and Spanish.

Partial The calculators and UI are straightforward to vibe-code, but accurate fit, PSU, and bottleneck checks depend on a maintained database of component specs and official game requirements.
What it would actually take: Build a web frontend with a structured database of PSUs, GPUs, cases, coolers, and CPUs (dimensions, TDP, connectors) plus scraped or curated official game requirements. The bottleneck test needs benchmark-derived scaling data to be meaningful. The hard parts are gathering and keeping that data accurate and current, and validating the bottleneck logic against real measurements, which requires PC hardware knowledge.
