I use xpenology on my old gaming rig as server (no GPU). And i love it. Had unraid before was also very good but diffrent. My main usage is to store Family Files and Photos and the best software ist Synology fotos for me.

i will have a look thanks.

With my test experience now your 100% right. can i store permanent data in the ubuntu vm there and install my own software permanent?

Thats the next thing i gonna try. In my work we have the possibilities to accces windows in browser and its realy fast. i just want the same for linux. my last try was to access docker Container with guacamole. but i vould also try to acces my root server itself with vnc and guacamole. the topic is realy interesting because the diffrent possibilities have different pros and cons.

Interesting idea. I know this tool from work but as desktop client.
