Can something in a water cooling system break then spray water everywhere
Yes, but it's usually a leak-drip rather than Niagara.
Could do a lot of damage - like blow your mobo, vidcard and PSU.
It's often the result of moving pipes (which aren't infinitely flexible)
about, loosening clips, etc.
If so how often would it happen?
Prolly never if you take care and check things once a fortnight.
