Carbide 678C Mid-Tower Chassis


The front of the chassis is substantial as it has a hinged door that opens from the left. The lower portion has a gray corsair logo but otherwise not much to see. You barely see the silver feet for the chassis poking out and reflecting on the photo bench surface. In the topmost area, we can scarcely see the gap between the top and front panel, which exposes the black inner plastic. The front door is held closed via magnets embedded into the panel itself.

The top of the 678C has a large ventilation area, but by default, it also is adorned with a large solid plate with sound deadening material to reduce acoustics of the chassis. If using top-mounted cooling, I would recommend removing this. Corsair preinstalls a fan here, and I cannot imagine how it would breathe very well with this panel in place. The I/O is found to the right-hand side top adjacent to this ventilation area, which we will check out now.

The front panel I/O is stuffed quite well and even has redundant power LEDs. To the front, you will see the wide rectangular semi-opaque plastic. This piece is used to light up blue when the system is powered on. The power button itself also illuminates when powered.

The I/O loadout is as follows:

  • Power button with integrated power LED
  • Reset button
  • 2x USB 3.0 (USB 3.2 Gen 1) Type-A ports
  • USB 3.2 Gen 2 Type-C port
  • Combination microphone and headphone 3.5mm jack

The I/O is more than competent for the chassis and quite common for chassis of this level. The combo mic/headphone jack, however, will require an adapter if you plan to use it for a two-wire headset.

A tempered glass door covers the left side of the chassis. The tempered glass door uses magnets to stay shut, which is nice as it somewhat eliminates the ordinary fasteners at each corner used to affix a panel. However, there are still four fasteners on the rear edge which fix the hinge to the glass. The glass has a slight tint to it, not overly dark but more smoked. You can also see inside with many of the cases features visible, but we will get to those shortly when we dig inside.

The rear of the chassis is reasonably standard, with all of the parts being where you would expect them. The chassis has slotted 120mm and 140mm fan mounting, but come preinstalled with a 140mm PWM fan. The 678C also has the standard seven expansion slots with the additional two for vertical mounting. If vertical mounting, you would need to purchase the PCIe riser separately as the chassis does not come with it, but that is relatively standard as most cases do not. The gap between the IO Shield cutout and the cable management panel side is not huge and telling that there may not be a large amount of room back there. Let's take a look at the cable management side now.

The cable management side panel is solid steel and painted chassis color white. This panel has no ventilation or any special features here. The panel shows a minimal gap to the front door panel when closed and creates a solid white aesthetic.

The bottom of the 678C has a full-length dust filter in place. The dust filter removes from the front and requires the front door to be opened for it to be removed. The opening is massive to allow for large PSUs along with bottom mounted cooling to breathe as expected. The corners are where you will find the four circular pillar style feet, each having its round rubber pad to avoid skidding.

Removing the filter, you can see the massive ventilation opening at the bottom. I am quite sure we are close to more open space than metal in this chassis as its almost entirely free for airflow. One area that's not fully open for airflow is the front panel door, which now you can see the cutout across the bottom, which is the front intake fans only way to ingest air. This opening is quite limited and requires the air to move up and into the fan, which is not ideal, and with the door closed, the 678C will suffer a bit from a lack of incoming airflow.
