“The Seidon 120V is Cooler Master’s new water cooling kit with the best C/P ratio. The compact 120mm radiator virtually fits every case. Thanks to a 120mm PWM fan with a wide RPM range, Seidon can operate silently or unleash a powerful cooling storm at PWM controlled command. The durable FEP Tubing provides the advantages of nearly no moisture absorption, high thermal stability and high pressure tolerance.” ~ Cooler Master

Most 120mm setups can be install in any mid to full tower cases, but if you are looking to install a AIO Liquid Cooler you will need to read all the specifications to make sure it will work for you.
