Who needs a custom water-loop when you can stick an AIO and call it a day!
Down here in Australia, an AIO is a must have, especially with 8th gen skylake refresh chips, since the temperature around here can get up to 40°C! Originally I was going to go with a WINDFORCE card, but that would not sufficiently fit within the Mechify C. The RTX 2080 could only fit there with less than 10cm clearance, so any 15mm slim fit Noctua Fans would have to go in the outside between the front case panel filter, regardless, going with a WATERFORCE card means I can get a card that's OC'd out of the box as well as maintain temps of less than 50°C while gaming! Only limiting factor is the VRMs reaching on this revision z370 motherboard 55°C causing the IO shield to overheat the USB 3.(1?) ports, as well as mounting the radiator at the top just being a close tight with the Corsair H75 AIO, first world problems right?
The Corsair and Noctua fans (My preference is that high air-flow = high performance) are silent! Only when it's night-time the pumps are somewhat audible but that doesn't matter if you're wearing headphones.
