Pairing OMV with plex

Hello everyone.
I’ve been trying to get plex to work on my openmediavault server for a while now. However: sharing and updating plex is not really working.
Since plex is not natively supported by omv I can’t really be too mad at plex.
To get around that I thought that I could run a small box with a plex server on it that takes all the data from the OMV-Nas.
Can you recommend hardware and software aswell as a rough guide for that project?
Feel free to link to other entries if I’ve missed any of them.
Thank you in advance
Sayonara!
