I've been building this over the past few years. I left my job working on Google Earth to make a 3D PC builder. We have quite a few users so it's able to fund our team but I realized I never shared on HN!

Could you build this?
Partial The UI, compatibility rules, and retailer price pages are buildable, but the product depends on a large curated parts database with thousands of 3D models, live pricing, and FPS estimates. Building and maintaining that data and the performance model is the moat.
What it would actually take: The stack is a 3D web frontend (Three.js or similar) backed by a normalized parts catalog, a compatibility rules engine, and price-scraping or retailer-feed pipelines. The hard parts are the 3D asset pipeline for thousands of components and an FPS estimation model calibrated on real benchmark data. That takes 3D artists, data engineers, and benchmark-testing resources, plus years of curation.
