How easy are the Phoenix to mod? Could you add your own fittings/tubing without too much hassle? I recall some people doing this with the Predator with reasonable success. Looking at one of these for an ITX build but I am not a fan of the tubing/QDC.
From the pictures and videos I have seen is less moddable than the Predator. Someone could correct me if wrong, but seems there are no fittings to the rad nor to the CPU block to allow changes.
Predator on the other hand you can build whole custom loop around it as everything is just compatible with any standard gear.
Everything can be replaced easily even the cpu block to monoblock. Same applies to tubbing etc.
For the MLC i do not see that unfortunately. Imho try to find a rev 1.1 Predator 360. Alternative get a kit. I know that DCC pump is superb attached to the rad for space saving, but...
I have a predator 360 and I will keep it until it dies. And then mod it
