Interesting use. Unfortunately I haven't found any usage like that. Maybe a home automation system and an Arduino interface?

I checked the XDA forum a bit, I found this but I'm not sure on how to unlock the bootloader, install TWRP and flash the ROM?

I had once bricked this tablet while playing around with rooting it and I had to take it to a repair shop. So I'd appreciate if there were working unbrick instructions and also working instructions on how to install TWRP.

What kind of servers could I run on this spec?

If you have got a Nvidia video card and you want to use it, use X11. Other than that use Wayland unless you encounter any bug or incompatibility.

Wayland is more modern and actively receives updates and features.
