Wow, we only vacuum once a week, that's it. Maybe its because my tower is on my desk? Or our air is just really clean for some reason...

The latency isn't an issue, the timing becomes an issue because you don't have a clean signal at some point, meaning the signal will arrive "spread out" over time. If it spreads to the next signal, your GPU isn't recognized anymore.

But as long as.that doesn't happen, there is no latency or performance decrease.

Depends in how clean your room is. I have a case without dust filters and it's been running for over a year without any visible dust accumulating.

Also it's mounted up high, the further you can get from your floor the cleaner it'll be.

Nope. As long as your signal still gets through without timing issues, everything behaves fine.

You don't really need any airflow there. The only thing that gets hot there is memory, but that is already cooled through the PCB (good heat conductor because of the copper), which is cooled by the regular heat sink.

free libre open source software.

Basically software by the people for the people controlled and kept in check by the people.

what kind of prof is that?

Sorry for the late reply but yes, this works on Lineage, one of the reasons I'm using it!

SEO isn't something google invented, it was just a result of their actions.

A lot oft ROMs allow you go completely disable Internet access for a certain app. Disabling the data collection toggles in GBoard and disabling internet access for GBoard, Play Services, Play Store and the Google App should prevent most logging.

Almost all Linuxes are really private. Because of your ethics and morals, I would probably switch to Debian or Arch, and use Flatpak where possible to prevent apps from spying on one another and reading files from other apps or your system.

Kicksecure, Whonix, Tails, Qubes, ... exist but they're not needed and to much of a hassle for day to day use for most people.
