The Obsidian Series 800D is built to last through years of motherboard, power, memory, cooling, and component upgrades.

The steel structure has a matte black coating both inside out and is finished with a brushed aluminum faceplate for a professional look that’s both serious and awe-inspiring. A windowed side panel makes it easy to show off your work.

Here at FrozenCPU we took the best of the best and incorporated it into a simple yet performance geared liquid cooling system.

First we took the XSPC Dual 5.25" Bay reservoir and married it with the MCP-655 pump. The MCP655 pump is a high reliability, high pressure industrial pump, featuring a 50,000 hour MTBF (5 year lifetime). Such reliability is afforded by the unique design of this pump, which contains only one moving part: the magnetically driven spherical impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards.

Next we incorporated a variety of options for the CPU block. During conception the Swiftech GTZ was our choice but we have left that up to you to decide below!

The radiator was chosen due to it's unwavering success, the Black Ice GTX Xtreme 360. The Black Ice GTX Xtreme Radiator brings true next generation PC Radiator technology to a higher level of performance. Using the new GTX platform, the GTX provides twice the liquid heat transfer surface area with a unique pre-cool/aftercool coolant flow configuration which increases heat transfer efficiency and internal system flow rates. The first effective dual core PC radiator. High performance and quiet operation no longer need to be a compromise.

Addition blocks can be added to this system quite easily as well. Don't be shy to extend this system to cool more if your heart so desires!

Notes: Picture shown with Swiftech Apogee GTZ, this can be replaced in the options below!

Chassis Features

• Four easily accessed hot-swap drive bays
• Removable CPU backplate panel for easy heatsink installation
• Isolated cooling zones prevent heat buildup
• Unique cable routing holes guarantee a clean and clutter-free installation
• Three fans included, with the ability to add four more 120mm fans
• Tool-free optical drive installation makes building a system faster than ever
• Two year warranty with Corsair’s world-class customer service and technical support

Three Isolated Cooling Zones
The power supply compartment, main compartment and the SATA bays each have dedicated cooling subsystems to prevent heat buildup.

A dust-filtered 140mm fan draws in cold air at the bottom of the chassis and exhausts it at the rear and top. This clever design forces fresh air directly over the graphics card and CPU. The SATA hot-swap bays are cooled by a separate 140mm fan which vents from the chassis via a sealed chamber and prevents the heat generated by the drives from entering the main compartment. The power supply compartment has its own dedicated intake and exhaust, also isolated from the main compartment.
Advanced Features for Extreme Flexibility
A four-drive SATA hot-swap drive bay sits in the front of the case, making it easier to install or swap hard drives on the fly. A unique cable routing system virtually eliminates cable clutter that can impede airflow. The tool-free design allows for easy entry, easy access, and quick installation of 5.25” drives.

The case itself is amazing. You can read the reviews of it elsewhere--it''s peerless. This is a review of FrozenCPU''s custom build. It''s a ton of money, but if you tally up the parts, and throw in at least a few hours of labor, it works out. The FrozenCPU guys made some small changes to my case: three 1k-2k rpm Noiseblocker M12-P fans up top instead of the slower 1200 rpm fans, a Lamptron FC4 fan controller, and then a reservoir change. Instead of the Primochill Typhoon III, which is pretty tough to work with (and believe me, I tried), the guys suggested the EK D5 X-Top pump top for the 655, and then a EK-Multioption 4-port RES 100 Rev. 2 perched on top of that. I have a tube with a dangerden fillport going into the top of the reservoir for anger-free filling and de-bubbling. And a T-pipe with another tube and fillport for easy draining. I think both the reservoir and the T are slowing down the flow, but oh man it is so handy. In the loop I have a QX9650 at 4GHz and two PowerColor 5870s with the factory-installed EK waterblocks. Load temperatures are amazing on the 5870 (never above 55C), and acceptable on the cpu. On hot days (when my home office is warm), the CPU will stay in the low- to mid-50s while playing BFBC2, but might briefly spike to 65 (its max). With ambient room temp of 77F (yes, it''s a bit warm in my office today), idle temps are 35-40C on the 5870s (as indicated by EVGA Precision), and 36-40C on the hottest CPU core (Core Temp). Some other notes: double check all of the fittings, as things loosen up during shipping. It comes with plenty of luxurious Feser tubing, so you don''t need to order more. My fans were rubbing sometimes, and I discovered it was because the screws that go through the top of the case, through the fans, and then into the radiator, were a teeny bit too short, and they were compressing the fans, causing rubbing. But the case comes with bags and bags and bags of screws (all black, which is a nice touch), and one of the bags had screws that were about 2mm longer--perfect.
