Let me start by saying that the Thermaltake Divider 300 TG ARGB is a beautiful case. In my humble opinion, it is one of the most functional, clean designs Thermaltake has produced in recent times. Just look at the color-matched framing and shape of the glass panels, split side panel, and perfectly centered and color-matched fans in the front, all wrapped around a solid steel frame—yes, please!

On top of that, the Thermaltake Divider 300 TG ARGB offers a modern I/O that is on point, ease of assembly, and plenty of room for storage for those who want to add lots of drives easily and without compromise. I was even positively surprised by the noise results for the system; that said, temperature results put it right in the bulk of cases we have tested with this component setup.

So all in all, that sounds great, and anyone looking at this case would be stoked to build in it. Unfortunately, there are two big drawbacks—one is the fact that a side-mounted AIO setup will force you to choose between a short GPU or spend money on a PCIe ribbon cable for vertical installation, which caps access to any of your motherboard's 5–6 other expansion slots. This is only made worse by the fact that air-cooler compatibility is not as good as with most classic mid-tower cases out there, as we have been using this test setup for over a year now with no issues. Within the Divider 300 TG ARGB, it would absolutely fit as well were it not for that fold in the steel of the side panel. It is rather disappointing to see such a beautiful chassis with a layout that could be quite the catch for liquid cooling and ARGB fans with these limitations. These issues could have easily been eliminated by making the chassis 10 mm wider and getting rid of that fold on the side panel, along with a few tiny tooling tweaks for the side air/AIO mounting position—you would suddenly have a chassis that is compatible with air coolers of at least 165 mm, as well as the room required for liquid cooling on the side without blocking the GPU.

I am excited for the other form factors of the Divider series, as each case in the family will be vastly different. That having been said, the Thermaltake Divider 300 TG forces way too many component layout and sizing compromises to recommend over the slew of other cases with ARGB fans and a built-in controller, even if most don't look as beautiful as the Divider 300 TG ARGB.
