I JUST got the exact Chuwi hero box you mention in this post for $150 a few days ago and I'm very impressed so far. It has Windows 11, a basic but good enough Intel processor, 8 GB memory and a 256 GB SSD soldered right on to the motherboard with room in the box for another SSD.
I have a Pi 3 and a Pi 4 and I just retired the Pi 3 since I got the Chuwi which is Much faster and has Much more storage. I can leave the Chuwi on all the time, like I did with the Pi's because it draws very little power.
Still, I may get the Pi 5 just to see what it can do. I'm just finding out about the Pi 5 from your post so thanks for that! :)
That box is amazing, I wish it shipped with 2.5Gbe though.
