New server and client help

[Magg66]

11th gen Intel and newer?  Ryzen 5000 and newer?

As for clients, it depends on your budget.  I personally prefer Android TV devices (except Fire OS devices).  Roku's devices are also solid.

Thank you for all the help.

I had a look and what I found is:
- i3 12100F
- Gigabyte H610M H V3
- 32gb DDR4 3200 CL16
- ASRock Arc A380

How big m.2 would i need for os, docker and cache? Would 256gb be ok or should I get bigger one. 

I’ve also looked at chromecast with google tv 4K. Would it be ok? Most people of course recommend nvidia shield but if possible I wouldn’t want to spend so much especially that server will cost a bit as well. 
It would be connected to receiver but only 3.1 system and 4k tv.  

Would you recommend Ubuntu as os and jellyfin in docker with arr stack?
