A Closer Look - Inside

Both openings on the sides come with small dust filters on the vented portions. Once again, the magnets are too weak and these will come off easily as you handle the panels.


The interior of the Thermaltake Ceres 300 TG ARGB is laid out traditionally with a metal shroud cover keeping the PSU and any cable mess away from the interior chamber. Thermaltake has placed mounting holes for vertical GPU placement here, giving you the flexibility you need to place it in the best possible spot no matter the dimensions of your pixel pusher. You may remove the side covers of the shroud to either gain access to the dust filter or to replace the portion with an LCD screen. In the rear, everything is pretty ordinary, with the exception of a big cutout at the top, above the CPU cooler bracket opening. This should really be covered by a grommet as well, just to keep things as tidy as possible.


Unlike the Ceres 500 TG ARGB, which comes with three mounting trays as well as a HDD cage, the 300 series sports a single mounting tray. This means it can only hold up to two drives, which is a stark difference. While this may be alright for some with NVMe SSDs taking over, it still isn't representative of the competitive landscape, with other cases of this size and price segment offering more. There are four Velcro straps holding the cables in place. Their presence is great, but again Thermaltake has simplified in comparison to the larger, thicker and easier to use variants found in the 500 series.


On the bottom, in the front, there is just room for a potential 120 mm fan on the floor of the chassis based on the mounting holes. But as Thermaltake does not mention support for this, try installing one here at your own risk. Thermaltake is the first brand we have seeing that is completely forgoing 3.5" storage possibilities in this area of the chassis with their reasoning being that users no longer need the additional storage space. Above that, there are the two 140 mm fans set to pull air into the chassis from the front.


In the rear the PSU bay is pretty straight forward, but features a plastic rail on which the installed unit will rest. Above that are the expansion slots inside Thermaltake's unique, rotatable frame. And, in the very top, you can clearly feast your eyes on that third 140 mm fan. The interesting aspect here is the fact that the leads coming off the unit are very short. While the thought was surely that this would help with cable management, it actually tends to make things a bit more difficult as you are locked into using pins on your motherboard that you can reach instead of being flexible in where to route connections to.


Thanks to the width of the Ceres 300 TG ARGB you can easily mount your AIO here without really having to worry about it colliding with any components as Thermaltake has offset the mounting holes for the fans or AIO as close to the glass side as possible. You may have to get a little bit creative to hide any wiring if all you are installing are fans, as there is only that big hole towards the back and a small cutout at the front corner of the chassis.


The connectors for the case are all of the default variety with individual pins for reset, power and LEDs. Thermaltake does go the extra mile by offering flat-band cables for the USB leads, which should make cable management a little easier.
