I bought this box and opened it up to find a lot of interesting things. For example, the specs are good, the circuit board is more versatile than other boards.
There are two USB 2.0 ports and one USB 3.0 port, and the heat sink looks great. spec
 
I built a Debian 13 image as per @Nick A's instructions and burned it to a micro SD card, and booted it with this box. Unfortunately, the screen went black with no progress.

Getting video acceleration is realtively easy in bookworm, but making it work in Trixie would be newsworthy

After wanting to use Debian 13 (Trixie) @Nick A suggested trying to build it myself, and this was my first experience building an Armbian image. I encountered some obstacles, but I got through them.
 
I saw that the model was mentioned branch v20251014. I tried building it (Mate Desktop), which as build smoother than (v20250306) before. I tried booting it with this box (Transpeed 8K618-T)  and and found that the wifi was not visible. I followed the troubleshooting methods in the previous thread solved it. I have installed additional IR remote and OpenVFD. Now everything is smooth and happy.
 
The only thing left is the video acceleration, but that would be difficult because it is beyond my ability.

Finally, thank you, @Nick A
