The right place for gaming and mass-parallel workload GPUs is outside of the case, on a flexible cable carrying 16 channels of PCIe v4 or 5 or whatever and a good ground. Selling the GPU in a case with appropriate power supply and cooling adds relatively little to the cost of a high-end GPU, and the marketing is obviously all about maximum performance unconstrained by your PC's form factor, without having to make any decisions or tradeoffs except money for speed.
