Looking at the interior of the Eclipse chassis, we found the layout to be very similar to that of the Thermaltake Soprano except for some noticeable changes in the area of the 3.5" drive bays. After looking over the four external 5.25" bays, which utilize a screw-less rail mounting system, we moved onto the 3.5" drives. To remove the 3.5" external drive cage, simply push the lever backwards. The removal of the internal 3.5" cage is also very easy, as it simply requires loosening of the bottom thumbscrew and then pushing down on the lever at the top of the internal cage. To install a hard drive in one of the five internal 3.5" bays, simply insert the drive into the respective bay followed by securing it in place with the included thumbscrews. To assist in noise dampening, on both sides of the bays are rubber grommets.
At the rear of the case, are the tool-less PCI slots that simply snap the expansion card in place followed by a tool-less 120mm exhaust fan slot. Unfortunately, the stock fan is a standard black fan with 4-pin molex connector; however, we decided to replace ours with a 120mm LED fan to match the blue lighting on the front bezel.
