The design of the cage isn’t very convenient, either:

You cannot install 5.25” drives if the vertical 3.5” bay is occupied. A HDD in that bay would block the access to the fastening holes on the right. The faceplate of the 3.5” bay is fastened right on the cage:

This saves the user the trouble of more manipulations with the front panel. It is also easier to remove the faceplate this way. As I wrote above, there is an additional cage for two HDDs under the main cage.

It is located in the best possible place, right behind the intake fan, so you shouldn’t worry about the thermal conditions of your HDDs. The fan has a diameter of 80mm and blue LED highlighting:

To the right of the cage there is a braid of cables going to the front interface connectors:

Thermaltake must have taken the cables from some other system case. Otherwise I can’t explain why they are two times the necessary length. Another drawback is the use of a cumbersome Molex to connect the front fan:

It just takes too much space which is so precious in such a compact system case.
