Could you build this?
Partial The 3D case builder and UI are vibe-codeable, but physically meaningful airflow results require CFD expertise and accurate fan and case models from manufacturers.
What it would actually take: A credible version needs a 3D editor (for example three.js or Unity) plus a CFD backend, such as an open-source solver like OpenFOAM or a lattice-Boltzmann GPU solver, with thermal modeling for CPU and GPU heat. The hard parts are validating the simulation against measured case data and licensing or measuring real fan curves and case geometry. That requires CFD and thermal engineering expertise and some hardware testing.
