The EK-Quantum Reflection² PC-O11D XL D5 PWM D-RGB is a custom water cooling reservoir, routing, and pump solution that seamlessly fits into the front of the case. This waterway is also equipped with 6 innovative push-in ports that come with female G1/4″ threaded adapters. The idea is that a user can assemble the whole radiator + fittings + tubing and use these push-in adapters to simply slide it into the distro plate.
