Hi @MaLd0n I just became a premium user (via Paypal). The parts for this build are arriving in a few days. I ordered all parts but not the CPU cooler. Because I live in a very humid and hot part of the world I would like to add a 420mm water cooler with a little trouble as possible, ideally the Corsair CUE H170i ELITE but it has and LCD so I have a feeling it will not work. Would a ARCTIC Liquid Freezer II 420 work? Could you please recommend something that would work with as little trouble as possible. If nothing in 3 fan 420mm , in 360mm 3 fan okay. Thanks for all your help so far!
