Sound and power consumption. At least in my case those are important if I was going to store data at my mothers house. Power consumption might not matter that much, but HDD sound definetly does. And even with spinning rust hardware cost would be somewhere around 250€ compared to ~20€/month of cloud storage.
YMMV, in my scenario it’s just easier to use a cloud provider.








You can see metal changing colours due to temperature, those are definetly soldering irons except the top right one which is a hot air soldering station and (IIRC, I have the same model) it goes up to 550C. You don’t want to hold any of those on the business end when they’re running.
