What to do with inherited server?

Hey everyone. So I just inherited a Dell R720 from work. I don’t know the full specs on it yet, but it’s got a 24 core processor and about 380 GB of memory. I need to buy my own drives, though. I honestly have no idea what to do with this. I’ve dreamed of having a home lab, but only ever thought about hosting a Unifi controller and a plex or jellyfin server. I’ll probably put Proxmox on it to manage everything. What recommendations do you all have for making use of this server? I’m honestly open to anything!
