Opening up the case reveals the complete black interior of the Carbide 400R. The inside is quite large and roomy. The multitude of holes, completed with protected rubber covers, helps for even better cable management from the front to the back of the motherboard tray.
On the bottom of the case are four rubber feet for the PSU as well as the support for a bottom mounted 120/140mm fan. Moving up the rear of the case are your four protected water-cooling holes, plus 8 expansion slots with slotted covers and thumbscrews for airflow and ease of installation.
Moving further up the rear is the 120mm exhaust fan, motherboard I/O slot and CPU cooler cutout.
Towards the front of the case is your hard drive cage which includes support for up to six drives; 3.5in drives can be installed tool free, while 2.5” can still be installed, but requires some screws. Each drive bay is equipped with its own hard drive tray, which is very flexible and even includes rubber pads to help reduce noise and vibrations from the 3.5” drives.
The four external 5.25” drives also have their own tool-free installation system, more on how it works later on in the review.
The internal cables for the case include your standard case hookups, plus internal USB 3.0 connection as well as your audio and Firewire hookups. Also included with the case is a USB 3.0 to USB 2.0 internal adapter, so you can use the easy-access USB ports for whichever your motherboard supports. Also included is the hardware, nicely sorted into separate bags.
