The interior of the HAF 922 if you might remember has an all-black interior the same as the exterior. The 912 is designed more for the value-conscious DIY system builder and has the standard SECC Steel color found on most cases on the market. The motherboard tray is well designed with two holes on top, three holes on the right side and two holes on the bottom of the tray for wire management.
There is a large hole in the CPU cooling area of the tray for where you can access the mounting bracket for the CPU cooler on the motherboard. This allows you to remove the CPU cooler without removing the motherboard from the motherboard tray. There are also loops all across the motherboard tray for wire management. This allows for the maximum control over the wires inside the case.
There are eight PCI slot covers on the case, seven in the normal position and one positioned above that for non-powered PCI brackets and or fan controllers. Above that is a 120mm fan. Below the PCI slot covers is the PSU area of the case. There’s a dust filter on the bottom of the case to keep dust away from the PSU.
The right side of the case is of course where the drive bays are. The top four bays are of the 5.25” variety. The top rack has a tool-less mechanism for installing a drive. You can move it up or down to change the location of the mechanism. The middle rack is rotatable allowing the four drives to mounted facing the motherboard instead of the side of the case. The bottom two drives are installed in the bottom rack. The floor of the case also has the 2.5” drive rack allowing for two 2.5” drives to be installed. Alternatively, you can install the rack below the case or atop the bottom 3.5” drive rack if you want to install long video cards.
This case is really designed for the longest video cards on the market including the Radeon HD 5970 and GeForce GTX 480 video cards. If you have a standard card such as the HD 5870 or GeForce GTX 460 you can install it without moving any drive racks. Installing a longer card requires moving the 3.5” drive rack but you still have the option of up to 8 drives with the included 2.5” drive rack and the 5.25” drives. As most people are using SSD drives this is an excellent compromise for the budget minded gamer wanting the most performance out of their system as you can install two of the HD 5970s in CrossfireX mode, install two 5.25” drives, install two SSD drives in RAID for the OS and install two SATA HDDs for storage.
