Ok, don't blame me, I'm going to make an extremely boring comment: If your digital life is on risk, better if you move the equipment or cover it when not in use. A power outage minutes before a storm, a design failure, a system malfunction, a foreign object jamming the mechanism => open lid during rainstorm => bye bye computer
I know, it's a very boring comment and is against my D.I.Y spirit. But some situations don't have space for experimentation or allow mistakes.
