^ I can back that claim of the H100 failing out on people. alot have had leaks and most just found them on almost every all-in-one cooler.
@ OP - please head down to the watercooling sticky, located in my sig and read up on it. Full of info and a CLC section dedicated to dealing and explaining about CLC's.
after using a CLC myself, I'd suggest going custom if you really want to watercool.
