Detailed Interior Features
The small details of the interior of a case can really make a difference on what it is like to use in the long run. Nothing is worse then buying a case only to find that the fans are so anemic that they require replacing.
Both of the front and the top use the same 200mm fan. Sadly there are no official specifications and from what I have been able to gather the included fans should be rated 96 CFM at 30 dBA. At the same time this fan can be removed and replaced with either two 120mm or 140mm fans. One other options that many users who use this case may want to choose is to run a 240mm or 280mm radiator for water cooling.
One unique feature about the 200mm fans used on the Obsidian 650D is that they are 200mm x 20mm rather the typical 200mm x 30mm. This means replacing these fans with higher performing fan especially in the front could pose a problem for many users.
The rear fan 120mm fan used on the 650D is also used on Corsairs all-in-one cooling products. It is a Corsair branded version of the D12SM-12 by Yate Loon and is rated at 70.5 CFM at 1650RPM. As with the other fans the the 120mm fan has also been installed with rubber grommets which help prevent vibrations from the fan transfering to the case further cutting down on the noise of the system.
Corsair has provided thumbscrews for each of the eight expansion slots. This allows users to easily upgrade their systems with new PCI and PCI-e based accessories without needing to use a toolset.
One side note about the drive caddies that are provided is that users should be prepared to use right angle connections for both power and data. I found that while building into the 650D that my power connections coming from the power supply where in danger of breaking off the PCB board of SSD that I used.
