Love reading threads like these. Have already discovered a couple of cool things in here to explore.

Here's what I'm either running now or in the process of standing up. It's very WIP, and nothing special, but maybe someone has some feedback/ideas. I'm aiming to have all the things I use contained in my rack, relying on cloud stuff as little as possible, mainly as a fun exercise/project.

Devices:

    * 6 x Raspberry Pis (1 x v1, 2 x v2, 1 x v3, 2 x v4)    
    * 1 x HP Microserver (ProLiant Gen8 Intel Celeron G1610T, 2x3TB in RAID, 1TB regular)   
    * 1 x Old gaming PC (i7 3770K, 24GB mem)    
    * 1 x Current PC (i5 12600K, 64GB mem; this is in the rack so that I can have a small, cleared desk, but is not hosting anything)

Uses:

    * Dev stuff:
        * Forge - WIP: Forgejo
        * CI/CD - WIP/TBC: Woodpecker CI vs Concourse CI vs Laminar CI
        * Container registries - 1 x my images, 1 x Docker Hub mirror
        * Deployments - WIP: Would love a FOSS Octopus Deploy clone. Working on my own primitive Ansible clone for fun, which might be good enough.
    * Home stuff:
        * Reverse proxy - nginx
        * Backups - TBC: Not sure yet. Lots of good options around. Probably should be doing this first..
        * Adblock - Pihole
        * Content aggregation - Basic Bash YT downloader (using yt-dlp), Deluge
        * NAS - Samba
        * VPN - WIP: Wireguard
        * Network control - WIP: some basic custom stuff to wake/sleep the microserver + gaming PC when not in use for power/heat reasons, initiate backups etc
        * Telegram bots - TG is my chat client of choice and I have a small .NET 'gateway' API I use to send messages from various bots (each representing different parts of my 'home lab') to my personal account
        * Monitoring/dashboards - TBC: haven't explored software for this yet
        * Log aggregation - TBC: haven't explored software for this yet
        * Network boot - TBC: Yesterday I started thinking of trying to PXE boot the RPis cause they're in one of those stacking towers inside my half-height rack, so getting to them is a PITA.
