Also eGPU. I have a tiny NUC-size system with decent internal GPU and a (physically much larger) game system with a slower CPU that idles at only a bit under twice the maximum power of the NUC. It would be handy to be able to just plug in an eGPU when needed. The power and cooling requirements of fancy GPUs are so much higher than that of CPUs that large cases designed around the CPU don't make much sense. Even the pysical stability of a large GPU in an ATX style case is not ideal.
