OPAM Hot End

Honestly it is overkill for the typical filament, but it is cool and nice to have.
There should be a warning with this set up, it will wear out your electronics faster as you must provide more current in order to keep the right temperature.
The pump provided is a fish tank pump and you can't really control the flow out of the box that is the problem.

The flow shouldn't matter. The issue I see here is that he doesn't have a way to dissipate the heat in the water. Long prints may present some issues without introducing a small radiator. Interesting idea, but I completely agree, this is overkill and adds unneeded complexity to your build.

An external radiator is needed, but I gather that's standardized in the PC water cooling circles. And this seems to be made to appeal to them.

As it is, I do question the need for this. Fan cooling works fine on E3Dv6s and Picos, I've run both up to 400˚C and the fins remain plenty cool enough to touch, and requires less parts to do so. But hey, if there's a benefit, then they're more than welcome to give it a try. I guess water cooling should be quieter provided the pump and radiator fan are chosen well.
