Corsair hydro H50.
Its a contained unit, however installation is not trivial, I had to fully remove my mobo to gain access to the backside of it to install the backplate for the cooler.
Furthermore the radiator/fan assembly is HUGE and doesn't "fit" anywhere in my case, and secondly the water tubes are too rigid to twist it enough to mount to the side of my computer.
Currently I have my computer on its side, case off, with my cooler unit hanging off the back of it. Its ghetto.
However, the desired performance has been reached.
