A Closer Look - Outside

Out of the box, the Thermaltake Divider 550 TG Ultra can be considered a large mid-tower chassis. It comes with full glass panels on three sides, which is a departure from the original Divider 500 series as it featured a main side with a diagonally split design. This is now gone in favor of a full glass panel. While beneficial in terms of maximum cooler height and visibility, it does remove the main reason for the Divider model name. And while the body is identical to that of the 500 TG variants, Thermaltake has cut a square into the front glass panel for the embedded display.


Taking a first look at the front, the glass is framed in black, and we see the three ARGB fans in the front. You may pull off the front glass panel to get to these cooling units. Gone is the fine mesh filter that protected these in the original 500 TG ARGB. The fans are secured to a removable mounting frame, so taking the whole contraption out and prepping it with fans and a radiator is likely easily done. Looking at the rear, the interior is clearly laid out in a modern fashion, with the PSU on the bottom of the chassis.


Thermaltake no longer splits the main panel in two diagonally with the top half made out of glass and the bottom half made out of steel. Instead, you will find a clean, single glass panel, which still looks great on its own. The glass is shaped nicely to further add to the overall look of the chassis. Turning the Divider 550 TG Ultra over, the split trend of predecessors continues, with the only difference two steels panels instead of a mix of glass and metal.


The embedded display has the same form factor as their Pacific R2 Ultra Memory LCD monitor kit and utilizes Micro-USB for power and communication.


In the rear, the Thermaltake Divider 550 TG Ultra comes with a removable PSU frame on the bottom, meaning you have to slide your unit in through this side. Above that is Thermaltake's signature motherboard expansion-slot bracket that may be rotated for vertical GPU placement. It comes with seven reusable covers secured by thumb screws. In the very top is a fourth 120 mm fan. This one is not ARGB and comes with black blades. Fun fact: While the sticker on the 500 series featured retired Thermaltake branding, it looks like these cases now feature fans with their current logo.


In the top, you will find another glass panel covering the whole area, so all major sides of the Thermaltake Divider 550 TG Ultra feature this material. Pulling it off reveals another mounting frame for two 120 or 140 mm fans. Alternatively, you may opt for a 240 or 280 mm radiator instead. In the front is the I/O consisting of a reset button used as an LED control switch by default, audio inputs and outputs, a large power button with an LED that also acts as an HDD activity indicator, and two USB 3.0 ports and a USB 3.2 Type-C plug. Thermaltake actually cut a substantial hole into the top glass piece to fit this panel, which is very nice attention to detail.


The entire underside of the chassis is protected by a removable dust filter, which may be pulled out the back of the Divider 550 TG Ultra.
