Thanks. What about a nibbler? This is the issue, and the mod I am attempting https://www.reddit.com/r/watercooling/comments/3qztde/how_to_fit_an_ek_predator_into_a_phanteks_enthoo/?st=j91zkb23&sh=a2cb945c
Well, it is a metal case.
Any tool capable of cutting metal will work, probably.
Still unsure of exactly what you need to cut out, but it really doesn't matter to us out here, because you're the one doing the mod.
I would suggest obtaining another case to practice on, before chopping up your Luxe.
