Yes, that's the one. It comes in 240mm and 360mm variants, both are great. And it is an AIO. AIO stands for "All-in-one", it's just not a CLC (Closed Loop Cooler) like Corsair's stuff which are generally considered to be bad by water cooling standards because they use sub-standard components like aluminium radiators and very weak and crappy pumps to save on cost. The Predator from EK is built with EK's own high quality water cooling components and is second only to full custom loops in performance.
And while it is easier to leak during installation because it's designed to be able to be expanded (thus they can't attach the tubes and such as well as with CLCs which are designed to never be taken apart outside a lab), it is no more...
