The Diablotek Fly is a unique case in terms of its composition. The Fly is composed of an aluminum-magnesium mix, which gives the case a very, very light design. It weighs in at only 7.7lbs and is by far, one of the lightest cases we’ve ever seen. The case can appear to be black at times, but the finish is more of a gunmetal/slate color. Other than the unique material and finish, the case has a pretty basic design.
The front panel also has the aluminum-magnesium mix along with some black sparkly wire mesh to accent it. There are four 5.25” external drive bays as well as a single 3.5” external bay. The front access buttons can be found between the 3.5” bay and the front 120mm fan grill (fan not included) and includes two USB 2.0 ports, audio/mic jacks, HDD/power LEDs, and power/reset buttons. Unfortunately this case does not have any USB 3.0 ports, which is something that should be implemented in newer cases.
The back panel also has the same gunmetal finish that the rest of the case does and has your typical rear panel accoutrements. There is the motherboard I/O slot, rear 120mm fan (included) and water-cooling holes found near the top of the case.
Working your way down the back you’ll find seven expansion slots with slotted bay covers, extra slotted hole for airflow, and a bottom mounted PSU slot. Both side panels are secured by two thumbscrews, which are nice to see, as not all cases have them on both.
