Corsair Obsidian 900D Build – Black’n’Blue w/ Custom Watercooling

Corsair announced the Obsidian 900D („Godzilla“) at the CES 2013. I received my test sample shortly after and published my launch review on in April. I really liked the chassis so I decided to use it as the basis for an upgrade of my private workstation. My goal was to build a system which is fast, silent, cool and is good looking. Therefore a custom watercooling loop was essential. I chose the following components at first (some components where changed in the meantime):


CPU: Intel Core i5 2500K /// OC’ed to 4500 MHz
Mainboard: ASUS P8P67 Rev. 3.1
Memory: 8GB Corsair Vengeance Blue 1866MHz
GPU: AMD Radeon HD 7970 /// OC’ed to 1200 MHz core frequency
Storage: Crucial M4 128GB & Seagate Barracuda.12 500 GByte -> Replaced with an ADATA SX900 512GB and an 2TB 3,5″ HDD
PSU: Corsair TX650W -> Replaced with an Antec High Current Pro Platinum Modell HCP-850 850W
Case: Corsair Obsidian 900D


CPU: Watercool Heatkiller 3.0 Nickel-Chrome
Radiatoren: Phobya G-Changer 480 V.2 & Swiftech MCR-360
Reservoir: EK-Multioption RES X2
Pump: Laing DDC Ultra
Tubing: Koolance 16/13mm
Fittings: 13mm (1/2″) – silver & Enzotech 90°-adapters
Fans: Noiseblocker 120mm XL1 & XL2
Control unit: Aquaero 5 Pro

Here is the first stage of the build:

Later I did some minor improvements. I guess that I can finish the system according to my initial conception (midplate, hard tubing, better fans, several covers for a clean interior) while upgrading the system to Skylake/DDR4/980 Ti this winter :)
