You can just look for a mini PC with the Ryzen 7 7840U / Ryzen 7 7840HS / Ryzen 9 7940HS if that's your goal.
The Z1 Extreme is basically just the 7840U with it's AI hardware disabled and tuned a little differently for battery life, but on a mini PC that's not super necessary. And the 7840HS/7940HS both do slightly better in the CPU area. All of them also use the same 780M iGPU too.
