im a new in selfhosted and got an old-old server

Hi guys, i'm a newbee in selfhost and one of my colleages hands me old server from corp guys. what i should try first and any recommends at it? at the moment i already install a proxmox and server specs is: preview.redd.it/x4ql12p91qmh1.png i wondering if torrents autodownload and photo/notes sync fits in it.
