Installation Steps
Removing Side Panels
Remove the thumbscrews and slide the side panel forward toward the front of the case to remove it. Corsair recommends removing both side panels during system assembly to avoid accidental damage.
Installing the Motherboard
Install your motherboard's I/O shield. Align the motherboard with the standoffs in the case and secure it using the included MBD/HDD screws.
Installing the Power Supply (PSU)
Unscrew and remove the PSU mounting bracket. Place the PSU on the bottom of the case with the fan side facing outwards. Align the holes and secure it with screws.
Installing PCI-E/PCI Cards
Remove the thumbscrews and the corresponding slot covers. Install the add-on card and secure it with the thumbscrews.
Installing 5.25" Drives (ODD)
Remove the front panel 5.25" drive bay cover. Insert the ODD into the drive bay until the tool-free latch clicks, securing the drive. To remove, push the tool-free tab.
Installing 3.5" HDD and 2.5" SSD
Place the drive into the tool-free cage until it feels secure. To remove the drive, pull the tabs to release.
Connecting Cables
Attach the case fan cables to the motherboard headers. Connect the front I/O connectors (USB 3.0, Power/Reset, Audio) to the motherboard according to your motherboard manual's pin-out diagram.
