Very similar to my setup as well. I have a Qotom with 5x2.5Gb NICs. It’s got a lower end processor - Intel Celeron J4125 but I haven’t noticed any performance issues with my 1.5Gb connection.
I’ve got my proxmox cluster and my workstation on one interface with a 2.5Gb unmanaged switch, and then on another interface a Unifi 8 Lite PoE switch with 2 Unifi AP’s where all the streaming devices, wife’s and kids devices live.
I’ll throw in my vote for Kavita. Works great. I read a lot on my phone so I just saved the app shortcut to my home screen from Firefox.
Mine machines are all named after Final Fantasy Summons/Espers/Eidolons/Aeons/Primals.
My main proxmox node is Bahamut. I try to pick a suitable summon that matches the host but that doesn’t always work.
Late reply, but I’ve got 4 proxmox nodes. TrueNAS with an HBA passed through, the arr stack, jellyfin, Home assistant, Nextcloud, bookstack, Unifi network application, Kavita, a windows VM with a 3080ti passed through that the kids can connect to using moonlight to play games on various tvs/devices. Various Linux distros to play around and test configs before I make any serious changes to my main desktop. Most recently set up graylog to pull in logs from pfsense and Unifi.
I have an insatiable thirst to just learn!
