As mentioned this case has four external 5 ¼” bays, two external 3 ½” bays and five internal 3 ½” bays. If you don’t have a floppy disk drive or a memory card reader you can use the external 3 ½” bays for installing more hard disk drives, so you can have up to five, six or seven hard disk drives, depending on the number of external 3 ½” devices you might have. The external 3 ½” bays, however, don’t use screwless mechanisms and also the holes available are in a position to match the holes on floppy disk drives, which are located on a different position from those on hard disk drives. Translation: if you install a hard disk drive on a floppy disk drive bay, you will only be able to add one screw at each side of the drive, making it to not be as stable as it should be.

As you can imagine from what we wrote on the above paragraph, this case has screwless mechanisms on the 5 ¼” bays and on the internal 3 ½” bays, as you can see in Figure 10. The internal 3 ½” bays are rotated 90º compared to the 5 ¼” bays.

Thermaltake V9 has a 120 mm fan between the front panel and the hard disk drive bays that glows red when it is turned on. To show it to you, we had to remove the plastic front panel from the case.

You can see two things in Figure 11. First, this case has a washable dust filter attached to the frontal 120 mm fan, which is great. The second thing you will notice is that all external bays except the topmost one come with metallic covers attached, which block airflow. For maximum airflow you need to remove these covers.

In Figure 13, you can see the front covers, which are meshed and come with dust filters.
