Mines nothing special, i5 10400 with 16GB of RAM and a 1050ti for video encoding. System runs TrueNAS Scale for Plex and Immich and has 44TB of drives running through a Dell H310 PERC SAS card. I desperately need more storage but I've been lacking the funds for new drives, I'd also need a 5.25" drive bay converter to hold the 2 additional drives I need in this case since all the bays are full, and another SAS card since this one's used up.
I'd like to move to Jellyfin but from what I've read it doesn't do as well for streaming from outside the network compared to Plex and half the users of my server are outside my network. So it works for now.
Also have a Raspberry Pi 5 running PiHole
Also a buddy 3D printed a fan mount for the H310 to make sure it doesnt overheat when doing file transfers and I slapped a Noctua on it
First thing I did when buying my '21 Toyota was remove the fuse giving power to the cellular modem. Is it still recording my data? Of course, but that's only a worry if I go to their dealership for service. If I ever need to actually do that (recalls for example) I'll remove the DCM module from the vehicle before bringing it in. There's a very good local shop near me that I'll bring it to for normal maintenance before letting Toyota plug in to the car and download my data.
Some vehicles this may not be possible, so if this concerns you, check forums about your vehicle if it is a moving spy machine before trying this because you might end up causing the vehicle to be put in limp mode because of some BS design choices.
