Alphacool Eisbaer 420 - world's largest and most powerful AIO cooler
Renowned liquid cooling specialist Alphacool offers the currently largest AIO water cooler for a moderate price while not skimping on component quality.
"The radiator is pure copper to better dissipate heat. Alphacool claims it's big and powerful enough to cool a CPU and more than one graphics card, which you can add to the loop thanks to its modular design.
Long-term use is one of the selling points. There is a quick-lock mechanism on one of the hoses that is compatible with "Eisbaer Ready" products, including its upcoming GPX-Pro graphics card AIO. Alphacool says you can also add custom liquid-cooling gear to the loop—the connectors are based on classic G1/4-inch threads and can be switched out as desired. Likewise, the hoses are 11/8mm.
Also unique to this cooler is a refill port. You can top off or replace the coolant inside if it's ever needed."

I'm using an AIO and weighing the pros and cons compared to a premium air cooler I prefer a no maintenance needed water cooling solution. The asking price of €145 for this monster seems moderate compared to competitor's offers.
