It is based around the constraint of the GPU size being the main driver of the case, and because CPU cooling is pretty good nowadays and M2 form factor for SSDs is so small, it really means you can get a powerful machine that can do gaming in a very modest form factor that is barely twice the size of the large GPUs on the market.
