Is there a hybrid in one case of a power bank, ssd and a single-board with WiFi 5 GHz, Ethernet 1 GE, USB 3.0 (if possible, able to make coffee)?

Question

Do it yourself

Greetings!
You have to carry with you almost the entire set listed in the title.
Watch movies on the way from your phone, upon arrival at the place, download the necessary data, it’s especially fun when there is no access to usb or it’s too slow for 2.0, you have to hard cut it to a laptop or docking station, from there it’s already poured over the network.
I want everything to be in one place.
I searched for Aliexpress, I find mostly bricks for hdd without a battery, or with regular WiFi and 100 megabit ethernet in fact. Can you give me a link or a search key?
If you assemble all this yourself (the case on a 3D printer), which of the single-boarders would you recommend? I think you need something where there is m2. WiFi at 5 GHz is desirable. Thanks =)
UPD1: I forgot the main thing - root access to the system is required so that you can configure scripts when connecting via usb, wifi, etc.

Recently I used this. It WD 1TB My Passport Wireless SSDcan do everything, built-in battery, there is a HDD version.
No, only ethernet, but inside is ordinary Linux with ssh. USB-Lan adapter can be made.
But expensive... Very expensive :)
