So I also had a 2009/2011 (can't tell exact year) iMac laying around and decided to install Linux on that before resorting to the Raspberry Pi, but I ended up corrupting the hard drive.

However, this morning, I woke up and found the iMac faced down with the screen shattered. I live near railroad tracks so the vibration of a passing train probably caused it to fall down.

Fuck it. In the trash it goes. I don't care about repairing it. The hard drive is corrupt and nobody wants an outdated Apple product.
