M1 watercooling questions

What's the max radiator size (length)? I'm thinking about moving a build with the EK MLC phoenix watercooling kit into the m1 and the rad+fans dimensions are 295mm x 133mm x 68mm. Is it possible to fit this on the bottom of the case, or would it have to be on the side panel? How much room would there be to move tubing around? (the phoenix has rather long tubes, and I'm cooling a gpu and a cpu).

I have the same question, I had to RMA my EK Predator and they are sending me this as a replacement.

Here's a build in the M1 with the Predator. Technically it sort of fits, but not at all what you'd call well. The Phoenix is very similar, except it uses fixed barbs on the radiator ports, rather than G1/4 threaded ports. That's going to make it that much more difficult to get in.

Ultimately, I would strongly caution against trying it. Stick with the recommended guidelines for the M1 (slim rads <35mm) and you'll have a lot fewer problems.
