This system and every other system on my network is run as either a Proxmox container or VM. I typically run Ubuntu for most of my projects. Apache for my web server with Nextcloud in a separate virtual server for my NAS. I prefer this method as it can automatically sync my phone and laptop akin to one drive. (Some of my music projects are large)
Here are some of the resources I used to deploy my proxmox config.

I use pihole as a DNS server. It is a solid DNS server with flexible support for tracking and blocking unwanted sites.

I have begun playing with Ceph to amass my storage together across multiple nodes. My documentation will follow. As of now there won't be much until I really get comfortable with it. This ties into my proxmox 3 node system that provides high availability to my resources. As well offsite backups to two separate sites that are completely automated.
