The water block exploded, blowing the front of the case out. It cracked 3 areas and some bolts and the cases design has the water cooling housed above the optical drive bays unfortunately... The hoses stayed tight so the fluid squirted out the front and down the front of the cases insides. Was quite the mess.
I heard the explosion, and cut power in under 20 seconds luckily. The block smoked for a straight half hour afterwards. Good times. Not holding the company accountable for my rug, or full value of the few parts that were damaged... so long as they settle this fast.
(Moneys not big to me, but principle is as long as it doesn't eat too much of my time up.)
