Don't try this at home
I recently had too much time and started cleaning my PC from the inside, leaving the side panel only leaned-on. Later that day I had a cup of Starbucks' Kenya coffee watching the Simpsons and - against my usual principles - put the half empty cup on the computer.

When it started to rain I turned in my seat to close my window, catching the computer case with my knee, which left the sidepanel tilted sideways. The now falling coffee mug found the panel to be a nice springboard for it's final jump into the casing, spraying lukewarm coffee all over the innards.
Something went 'click' and the computer shut down immediately.
Cursing, I unplugged all cables and connectors and started to take the machine apart. Virtually every single part, even the harddrives and the backpanel of my machine were caffeinated. It took me the better part of two hours to scrub the parts clean. I dried them off as good as I could and reconnected everything, letting it dry over night.
Next morning I connected the cables and switched the machine on - and nothing happened. Frustrated, I switched off and on again and noticed the power LED blinking very shortly. A third try let it stay on a little longer and the fourth made the CPU fan turn a few rounds.
Irritated and in some way curious, I repeated the switching several times until the machine eventually sprung into life, leaving a strange feeling of having done some kind of electronical heart massage. But, anyway, I revived my computer. For a day the box smelled like burnt coffee - apparently I hadn't found all the coffee contaminated spots - but it works fine.
All in all my original plan of cleaning the computer left it in a clean-as-new state, which I would never have cared to work for, voluntarily.
