If you haven't noticed, green and silver is the theme here. Besides the green plastic stabilizer pieces, there's also green drive locking notches on the drive cages.
Ok, before you go bezerk on the color scheme here, those notches are pretty damn cool if I must say. To get your drives in place, you won't even need a screwdriver. Just push your drives in, push the green notches forward and lock them down. That's all you need to do!
The middle green one you see there is in the lock position, while the ones above and below are open. This makes it easier to remove and install drives if you're constantly inside your case. And I thought the drive rails on the Enlight 7237 was easy to use!
Here's the 3.5" cage with the green locking notch also. Notice the extra space underneath the cage for another drive to be installed. The cage's bottom has these pre-drilled holes to get some hot air out. You can opt to put another drive there, or do some modding and get a fan under there for some extra cooling for your drives.
Along with the common bag of screws and accessories, the case comes with toolless expansion slot covers. Convenience is the key word for this case I guess.
The nipples for the case are a bit different too. Commonly you get the brass ones that you need to screw into the motherboard tray. By the way, this case DOES NOT have a removable tray, I'll take my remark about convenience away now. Anyway, the motherboard stand off for this case uses these different nipples that slide into the tray instead of screwing. At least that part is easy! I always have trouble with the brass ones staying in place while I turn it.
