The Disk Drive Bays
The 3R System T100 Valkyrie has three external 5.25” bays, one external 3.5” bay converted from one of the 5.25” bays, and eight 3.5”/2.5” bays in two cages. The top two 5.25” bays come with thumbscrews, but for all the other bays you will need to use regular screws.
As mentioned before, the upper hard disk drive bay can be removed for allowing the installation of longer video cards. During our review, the plastic parts that hold this cage in place broke. Updated 01/18/2012: The manufacturer sent us a second sample from its second production batch, where this problem was solved. The updated Figure 23 shows the latch intact, even after we installed and removed the cage several times.
It is possible to install a hard drive on top of the lower hard drive cage when the upper cage is removed.
Each 3.5”/2.5” bay is actually a small drawer. Two of them are very different, as they also allow the installation of 80 mm or 90 mm fans. The other drawers have a suspension mechanism for reducing the vibration generated by the hard disk drives.
The adapter for external 3.5” devices also allows you to install 3.5”/2.5” internal storage devices and a 120 mm fan. Therefore, you can have a maximum of ten 3.5”/2.5” devices with this case: eight in the regular 3.5”/2.5” bays, one in the 5.25” adapter (Figure 26), and one in the external 3.5”/2.5” docking bay.
