Questions on NC before installation

Hi there,
before having lots of work with installtion and setup of NC at home, I have some questions and hope you can help me.
I have 3 PCs. Let’s say PC-A, PC-B and PC-C. On PC-A I have almost all data for daily use. PC-B is running 24/7 mainly without monitor, sometimes on TV for movies and it is the syncstation for pictures of mobile phones (up to now syncsmb-App). PC-C is an old one just for backup starting every 2 or 3 weeks for syncing.
The idea is, to setup NC-server at PC-B, all phones can sync their photos via NC-app (even Ios). And PC-A with NC-client installed, can deliver updated files to PC-B when files updated or PC-A starts and PC-A receives smartphone-photos from PC-B for backup. To watch movies, stored in NC of PC-B, I install kodi with access to NC-webdav (at same PC).
Does all this work as I think?
Thank you

Like this, it looks reasonable for me. But which part are you worried about?

Thanks for your answer. I’m worried about lots of work to set this up and realizing then, that it does not work as I thought :smiley:

Depending on power and configuration, I don’t know how challenging it is, to properly stream video. Not sure if someone here has experience and can share some hardware specs.
