Fun contraption that allows you to pick some parts, namely the GPU, but the claim "Gaming-ready mini PC and eGPU for under $1000 USD" excludes the price of the GPU you need to purchase to make use of the eGPU dock (because that's the whole point). Let's not forget a display, which you may already have, but still.
With a half-decent graphics card purchase, you're in gaming notebook territory without a screen, battery, or portability.
Honest question, does this setup offer any advantage?
Mini PC eGPU docking stations were both uncommon and pricey just a few years ago, but the Beelink EX dock is one of the least expensive options thus far without needing to sacrifice features or quality along the way.
