Assembly

Installing the mainboard is an easy task, simply place the spacers in the appropriate locations and then secure the board with the included black screws. There is plenty of space around the large Prolimatech CPU cooler as you can see, so you should not have to worry if your favorite one will fit or not.


Installing a 3.5 inch hard drive is a simple matter of snapping the tray unto it and sliding it into the desired slot. With a 2.5 inch one, you have to remove one metal pin and are then able to screw the drive unto the tray and can then be pushed into the bay just the same.


Installing an optical drive is simply done by sliding it into place and pushing down the small clip at the end of the lever. The system is constructed like a seesaw. By raising the one end, two pins at the rear end are pressed into the screw holes of the drive, which then hold it in place surprisingly well.


The power supply on the other hand is simply inserted into the 600T by laying it unto the crossbar and then screwing it down. Nothing to see here - move along.


Once all the parts have been installed it becomes clear that the Obsidian 650D manages to route and hide cables just as good as the larger Obsidian series. All cables are being lead below the mainboard tray to their appropriate openings and then to the plugs. The hole in the tray allows unrestricted access to any CPU cooler backplate, so that you can exchange the cooling unit without removing the entire mainboard. As you can see, the entire cable mess is located here. This is made worse to the fact that white sleeved cables were attached to all leads coming from the PSU to achieve the black/white look.

Finished Looks

Closing the case up really meant pushing down on the panel behind the mainboard. Even though it bulged slightly under pressure, the large, spring loaded clamps hold it in place just fine. That is a small price to pay for a clean interior, but also goes to show that other cases with less than 20 mm of space have no chance in such a scenario.


Once the system is powered up, you are greeted by extremely quiet operational noise. The included fans are silent on low, but naturally become louder when running at full throttle. A few GPU BIOS edits later, this entire Crossfire based system was overclocked and extremely silent. (let us know how you like this build!)
