1 Problem
Most cases are static boxes. Mechanical motion beyond fans is nearly absent in modding, even though moving parts are the strongest visual magnet.
2 Idea
Build the rig as an orrery — a mechanical solar-system model: the CPU is the central sun, with component planets on brass arms rotating slowly via stepper motors.
3 Solution
A multi-tier circular frame, large bearings, power and PCIe routed through a slip-ring for infinite rotation; the CPU cooler stays fixed at the centre while the GPU and drives orbit. Rotation speed mapped to system load.
4 Feasibility
A slip-ring for high-speed PCIe 4.0 and 5.0 is a serious signal-integrity challenge; dynamic balancing and noise need work. But a low-RPM prototype has already proven the mechanical concept.
5 Current status
Prototype
Stage: Prototype
Prototype: the lower rotating tier and power slip-ring run reliably; now integrating the GPU onto an orbiting arm.
