That rusted, half-dead computer case is apparently all you need to run Linux. While Windows demands 16GB RAM and a quantum processor just to open a text file, Linux will happily boot on whatever archaeological artifact you've dug up from behind the shed. I've seen production servers running on hardware that belongs in the Smithsonian. That box probably outperforms half the cloud instances people are paying $50/month for. Just slap some Debian on it, SSH in from another continent, and watch it run for 7 years without rebooting.
