I think I nearly had a heart attack.
My wife spilled a whole glass of orange juice into the front of her G5 1.6. Knocked it into the thing with the back of her (admittedly high backed) chair
I swear, I nearly died. Fortunately for her, I was in the room. Yanked the power cord IMMEDIATLEY so that it wouldn't short out and fry something. Laid the G5 on a towel on it's front edge to drain the fluids out of it (again, luckily, none got to the PSU). After letting it sit for a minute or three, opened the side and removed the deflector and fans to assess any damage.
Once again, lucky for her, the fluid only came within a centimeter of her logic board. Went in with my iKlear pads (thank you, Meriddrew Enterprises!) and proceeded to clean up the mess. A fan helped to complete the drying process. My wife (and the G5) are EXTREMELY LUCKY.
So, a word of caution to anyone that doesn't know this already:
If you are going to have drinks in you computer lab, PLEASE FOR THE LOVE OF GOD AND ALL THAT IS HOLY, KEEP THEM AWAY FROM YOUR CPU. Get a big desk and set them on the opposite end of the thing. Also, be AWARE of your surroundings. Accidents happen, but you don't want them to cost you three grand.
As the Japanes would say, in many an anime, 'LUCKEEEE!'
