A Closer Look - Outside

Out of the box, the glass panel is protected by a plastic layer, and the aforementioned solid cover comes taped to the top of the enclosure. As the Carbide 678C is meant to be a silent enclosure, its overall design is understated and clean, with a door covering the front of the chassis.


Even though the front door is made out of plastic, it feels quite sturdy. Corsair kept it pretty smooth and has placed their branding on the bottom part of the panel. In the rear, everything looks pretty standard as far as the layout is concerned, but here, it becomes apparent that the Carbide 678C is slightly wider than some other mid-tower cases out there.


The main side panel is made out of glass and swings open for easy access. You may also take it off its hinges to put it somewhere save before commencing with system assembly, for example. On the opposite side, you will find nothing but a solid metal panel that is held in place by two thumb screws.


The door of the chassis swings open to the right and reveals a large dust filter behind which Corsair has placed a retail-grade 140 mm intake unit. You will find another dust filter lining the entire underside of the chassis; it may easily be pulled out through the front.


There is also a single 5.25" drive bay, which is quite the unusual sight these days, and it features a plastic pull-out tab for easy removal. Corsair has lined the interior of the door with a thin layer of sound-insulating material. Several metal pieces here allow for the built-in magnets to hold the door shut without the need for an additional locking mechanism.


In the rear, the bottom PSU bay comes with two sets of mounting holes, and as you can see, there is plenty of room next to it for cable management. Above that are the 7+2 expansion slots and another retail-grade 140 mm fan—this one is set to blow air out the back of the chassis.


Out of the box, the Corsair Carbide 678C comes with a magnetically attached metal mesh cover on top. Next to it, you will find a fairly large power LED, two USB 3.0, a single USB 3.1 Gen2 Type-C, and the usual audio I/O.
