To keep the cables clumped up together they have equipped the wholes with rubber. When it comes to the harddrives the are very easy to install and you can open up each HDD slot by pushing the buttons between 1-4 on the front of the case and pulling at the slot at the same time as you push it.
Each harddrive slot has ventilation holes inside the case to keep the drives as stable as possible and increase the lifetime. The front of the case is equipped with an intake fan (200 mm ) to get fresh cool air blown on to the drives themselves.
When it comes to the 5,25 slots you dont need any tools to mount the drives.
Thermaltake used this connector in the door hinges to power the fan, this way they didn’t need to have any cables and which makes the connection better and also a nicer and cleaner case. Inside the case you will find a small box with some accessories, like zip ties, motherboard speaker, headphone hanger for the case and also various screws and risers along with a few manuals.
As we can see there holes for the cables are placed right beside and below the motherboard. This is perfect for mounting cables nicely in the case, there is also plenty of space between the motherboard and 5,25 drives.
