As we mentioned briefly on the first page, this case comes with two hard disk drive cages. Each cage has three hard disk drive bays inside and each frontal 120-mm fan is attached to one cage. On the pictures we took (especially on Figure 4) the two cages were installed on the six bottom bays, but you can install them differently, if you want to. For example, install them on the top six bays or installing one at the top three bays and the other on the bottom three bays.
Also, each hard disk drive cage converts the three 5 ¼” bays where it is installed into three 3 ½” bays. So with the two cages installed you have three 5 ¼” bays and six 3 ½” bays. If you need more 5 ¼” bays you can simply remove one of the cages. Doing this you would have six 5 ¼” bays and three 3 ½” bays available.
One of the cages has a plastic bracket to hold another 120-mm fan (which doesn’t come with the case). This fan can be used to cool down your video cards, for example. You can see this bracket on Figure 10. It is important to notice that this fan should be installed only on an empty cage, i.e. on a cage without any hard drives in it.

We removed one of the hard disk drive cages from the case, see Figures 11 thru 13.
