/or caused a short, making something flame out?
along time ago, i was fooling with a 230W PSU from an old Pentium-S computer(133MHz CPU, 32MB RAM?, 2GB HDD, 4MB video card) cuz i was rewiring a fan in(the fan died, was replacing so at least it wasnt annoying when i was fooling with the PC) and it was still plugged in to the wall.....that was quite the shock

also, i plugged in a floppy drive wrong when i was on my Athlon Build(as some may remember), causing the red wire of that whole cable to melt the casing off(from plug to PSU) and scorched a number of things, and killed the drive
