A Closer Look - Inside

To access the interior, you first have to take off the top panel by removing several screws. After that, pull off all three glass-equipped panels. The metal ones are all held in place by thumb screws and can be detached independently. Thermaltake has done an excellent job covering all the mesh elements with dust filters.


Once the panels are off, you have unrestricted access to the Tower 100 from three sides. Thermaltake has struck a good balance between size and room for this ITX chassis, all while keeping dimensional ratios similar to the Tower 900. Taking a closer look at the front, you can now see the vent behind the motherboard tray with the rear panel removed. Thermaltake has also placed a shroud on the bottom of the cage to hide the PSU, which comes with a vent on which you could install another 120 or 140 mm fan. Actually, place the pre-installed rear case fan here for a push/pull configuration within the main chamber instead. Alternatively, you may place the two 2.5" SSD trays here to show your drives off to curious onlookers.


In the rear, the PSU bay comes with a mounting frame for the ATX unit. It offers plenty of space. As such, you should have no problems fitting a potent unit without going for a pricey SFX unit, for example. Due to the unique layout of the chassis, you will have to be creative with your cable routing, but there is plenty of room to either side of the power supply bay. Above that is the vent, which also acts as another hard-drive mount for either two 2.5" or 3.5" hard drives, or a 120 or 140 mm fan. The latter seems redundant as the case already allows for such a fan to be mounted to the rear case panel in exactly the same location. Another oddity is that the pre-installed rear fan will keep you from installing any 3.5" drives here, as we will see later on.


Both sides of the case give you access to the motherboard area, and you may easily connect cables or add a big GPU during assembly. The two aforementioned 2.5" drive plates are mounted to the side of the shroud, so while still visible from the outside, this location is a bit more subtle.


Looking at the ceiling of the Tower 100, you can see the two expansion slots for the GPU with plenty of space to the left, so you should be able to fit 2.5-slot cards without issue as well. Looking at the fan with the bare case, it once again becomes apparent that this area could fit a 140 mm unit. Alternatively, there is no reason why you could not install a 120 or 140 mm AIO here.


All the leads within the Tower 100 are sleeved black to keep things nice and clean. On top of that, the USB-C cable is of the flat variety to make routing it a little easier as well.
