Hanjung TR300 EX computer case tested

by on22 November 2011


The TR300 EX weighs 7.7kg. It measures about 230x496x482mm (W x L x H). We included the add-on on the left side panel in the measurements.


One side panel has a 12cm fan that will come in handy with hot graphics cards, SLI or CrossFire setups. Since the fan is technically outside the case, it won’t get in the way of tall CPU coolers.


Hanjung offers a version of the case with a classic, metal side panel, which is dubbed the TR300. 

We were pretty pleased with build quality of the TR300 EX, despite the few minor oversights. Hanjung used plastics of lesser quality in order to knock the price down, but the plastic is still tough enough and has a quality finish. The left side panel, entire top panel and parts of the front panel are made of plastics.

One of the minor issues we’ve found is that fact that users must break the metal covers on the expansion slots on the back of the case. While this is not a too hard task in itself, we’d advise users to get some gloves in order to do this. Namely, the covers are tough and not easy to take out. The TR300 EX has seven expansion slots in total.


Next to each of the slots is a blue square, suggesting that there is a toolless mechanism for expansion cards.

The thick blue cable you see on the picture below is that of USB 3.0 connectors coming from the control panel. This cable should be connected to a USB 3.0 connector on motherboards. Hanjung already showed how to take the cable out of the case.

Hanjung made sure that the case has adequate cooling and the TR300 EX comes with four fans. The first fan is on the rear panel; second is on the front panel; third on top whereas the fourth is the one sitting in the left panel.

The front panel fan is a blue LED one and will glow through the mesh grill on the front. There are also some LEDs on top of the front panel, which show up as a blue line when the computer is running.


The front panel has four 5.25’’ optical drive bays and there’s also the 5.25’’ to 3.5’’ adapter. As you can see, the front panel was spared of holding any keys or connectors. Power and reset keys were instead moved to the top control panel, which also holds the connectors.


All the connectors are lined up on the left edge of the panel. You’ll tell the USB 3.0 connectors from 2.0 by color, as the 3.0 connectors are blue while 2.0 ones are black.

The top of the front panel holds a hot-swap unit that’s used for quickly connecting 3.5’’ or 2.5’’ drives. The drives are removed by a simple tug, although it’s not as simple as it sounds since there is very little room for grabbing and pulling the drive with your hands. Hanjung could have perhaps used a mechanism for this - even a simple one would’ve done well. When the hot-swap unit is not used, you can use the room for smaller gadgets such as phones or USB sticks. In order to prevent slipping and sliding, Hanjung included a rubber pad in the accessories bag.

The TR300 EX also comes with fan regulation. Unfortunately, Hanjung used a button that only allows for two fan speed choices – fast or slow. All the fans use standard, three pin connectors so users can use their own fan controllers or connect the fans straight to the mobo.

The largest fan is a 200mm one and is hidden in the top panel.


The top panel hole (between the flaps and connectors) can be used to mount a 3-in-1 adapter and there is a cable hole in the middle of it. To the right is the fan speed control key.



The TR300 EX has rubber feet. Below the PSU is an air outlet, protected with a mesh grill filter. The filter cannot be removed for cleaning.
