Assembly

Installing a motherboard inside the Ceres 300 TG ARGB is done by the usual means of spacers and screws. There is a bit of room around all three edges of the board. Thermaltake does mention the ability to install E-ATX boards as well, but while technically true, you will loose the majority of your cable management possibilities in the process. This makes that mention in their marketing not really very useful to the end-user in reality. Even though the case is a bit more compact than the 500 TG ARGB, you should have no issues installing your fat and long GPUs into the chassis and that holds true, as the PNY GeForce RTX 4080 fits very nicely with room to spare for potent front intake cooling.


To install storage you may remove the metal tray. It can hold either two SSDs or one 2.5" drive alongside one 3.5" unit. Once filled you can screw the plate back into position using the captive thumb screw.


Adding a power supply is straightforward as well. Simply slide it underneath the shroud and use four screws to secure it to the chassis from the outside. There is naturally tons of room as Thermaltake has done away with the hard drive cage inside the Ceres 300 TG ARGB.


Adding the AIO is just as simple and the 240 mm unit easily fits in the ceiling of the chassis. That said, you will not be able to slide it all the way back with a fan in the rear in place. This means, if you attempt to go for a 360 mm unit here, you will likely have to - at the very least - downsize to a 120 mm rear exhaust unit to make room. Or worse, sacrifice that unit altogether.


With everything installed, the Thermaltake Ceres 300 TG ARGB does make a very clean impression. Within the interior, all the wiring is hidden away nicely and the well placed grommets allow for quick paths around the back as well. Here one can petty easily keep everything tidy, but we did have to use some additional zip ties to make it happen. The Ceres 300 TG ARGB does not have a lot of hooks for zip ties and the 3.5" drive will block you from running a wire up the rear edge of the case once the storage plate is put back in place.


Upon closing up the side panels, the solid one required an unusual amount of massaging into place. And putting a ruler up against it, it becomes apparent that it is bent out of shape by the installed 3.5" drive. This means that the one and only 3.5" capable placement within the Thermaltake Ceres 300 TG ARGB doesn't provide enough clearance. As soon as the drive was removed, the panel went on without any issues.

Finished Looks

Turned on, the Ceres 300 TG ARGB does look nice, but the lack of ARGB in the rear fan is unfortunate, since that would have really helped in light things up a bit more on that end of the chassis. A blue LED at the top will also let you know the system is up and running.


Looking at the front, you can see the lighting elements emitting from within the hub of each fan. As these are mounted behind the frame of the case, part of the glow is obstructed as well unfortunately. However, the clear glass panel allows you to view your hardware nicely and you are clearly able to see the ARGB lighting on the Thermaltake AIO as well. In the rear everything is exactly where you would expect to see it. Thanks to the hooks you will be able to bundle wires from the motherboard backplates nicely as well.
