Abstract
This article discusses the development of an educational VR simulator for assembling a personal computer. The aim of the project is to create an interactive environment that enables users to acquire practical PC assembly skills without the need for physical hardware. The use of the Unity engine, XR Interaction Toolkit, and OpenXR ensures realistic visualization and simulation of physical processes. The presented prototype includes 3D component models, VR interaction, and educational prompts. The project is designed to enhance learning effectiveness through immersive practice, improve knowledge retention, and support scalability for future educational modules. The work demonstrates the potential of VR in technical education and the development of applied ICT competencies.
