A Closer Look - Inside

To access the interior, simply swing the door open and take it off its hinges. The other, solid panel is held in place by easily accessible thumb screws. On the interior, you are greeted by an all white paint job. The metal shroud covering the power supply and 3.5" bay comes with a vent, and there are mounting holes for two 120 mm fans as well. However, Thermaltake does not mention these in the specifications, which has it seem as though the S100 TG is not meant for such a configuration. If you look closely, there are also cutouts for the SSD mounting plates to be placed here instead to show off your drives.


On the opposite side of the chassis, the motherboard tray comes with openings for cable routing and two of those aforementioned 2.5" mounting brackets.


Underneath the shroud, in the front, you will find a 3.5" cage that can hold either a 2.5" or 3.5" drive inside a plastic tray, and an additional such unit of your choice firmly mounted on top with screws. Above that is not much else besides the space for intake fans or a 280 mm radiator setup.


In the rear, the PSU bay is simple but certainly functional, with plenty of space to get a potent and efficient variant in there without issue. Above that are the four expansion slots with that black fan in the very top. Interestingly enough, that fan is much simpler than what we saw in the S300 TG. In fact, it is so old, it still sports the old Thermaltake logo.


Looking at the ceiling, you can clearly see the possible mounting positions for fans or radiators. Thermaltake has done an excellent job by placing them as far from the motherboard as possible, so you should not have to worry about components colliding during assembly.
