可交互的3D电脑主机拆解网站，含29个核心部件

Build an interactive 3D educational website that explains the parts of a desktop computer. Show a PC tower with a dark studio background and a clean light-on-dark interface. Use Three.js. Model about 29 core components (motherboard, CPU with cooler, GPU, RAM, SSD, power supply, fans, case panels) as separate meshes. Add a left sidebar listing components grouped by category with search, and a right panel that shows a name, short description and related parts for the selected component. Clicking a part in the list or the scene highlights it and focuses the camera on it. Provide an explode slider at the bottom that smoothly pulls every part away from the case along sensible axes and brings them back, plus orbit, zoom and reset controls. Add small animated labels for the selected part. Deliver a self-contained web project that runs locally. Done when every listed part can be selected, explained and separated in the exploded view without overlap glitches.
