If I really look back it all started with my own cable modem and router to save $10 a month on my Comcast bill. This led to DD-WRT and eventually OpenWRT on my routers throughout the years.

Then I spun up a media server for all my movies, shows, stand-up comedy specials, music, pictures, etc.

Had to have a hypervisor for virtual machines...

Next came my NVR camera system and VPN because FUCK having my footage ever leave my house.

...to name a few lol.
