I run a supermicro chassis with 6 3TB drives in a RAID6 using a dedicated hardware RAID controller. Old school for these days but works for my needs for now. Drives were free from a buddy of mine so until they start dying or I need more space, they’ll do. Then I have two 120GB intel enterprise SSDs for running Proxmox. VMs and LXCs are all on the spinning disks which surprisingly perform well enough.
The usual go to for self hosted password managers is VaultWarden. There’s no deb or rpm package but you can get it spun up with docker pretty easily. Any reason you’re specifically looking for “included” or packaged solutions? That’s going to severely limit your options.
