Live fast and play hard. That's the sort of motto you'll find exemplified in old school water cooling circles, the ones where wielding a pre-built kit or self-contained liquid cooler might earn you a wedgie. There's a certain satisfaction that comes from building your own water cooling setup, just as there is with building your own PC, and it's a market still being served by folks like Danger Den, which just announced the release of its highest performing CPU waterblock to date, the DD-M6 CPU Block.
