You could look into the new Minis Forum MS 01 (which is already on sale?): https://store.minisforum.com/products/minisforum-ms-01

Starts from $549 for the barebones with an i9-12900H. You could argue it is a better option as it has an internal PCIe slot for a half-slot GPU, which will be much less bulk than a mini PC + eGPU. Plus, it would probably be cheaper since eGPUs aren't cheap.

ETA Prime did a review on it the other day: https://www.youtube.com/watch?v=NUlptjU0vFQ
