Abused, But Working Hardware Stories?

RPI Geek writes "Everyone's heard the stories about people who, knowingly or unknowingly, abuse their computers. Personally, I've had a faulty power supply literally burn a hole through the motherboard, with the only ill effects being a dead PCI slot and USB ports. I'm curious as to what kind of abuse fellow /.ers have done or seen done to electronics while the hardware still worked afterwards. Soldered a broken keyboard PCB back together so that it worked fine? Taken sticks of RAM out of a running computer to see when it would notice? Overclocked a 386... to 386MHz? I'm interested in hearing any stories about abused-but-working hardware."
