The Cooltek GT-03 hails from our new ‘Gaming Tower’ series and offers an outstanding price-performance ratio. The case offers a variety of practical features that are certainly unique in its price range. For example, the GT-03 comes with an external docking station in the top and is equipped with a multistage 2-channel fan control for up to four fans.

The front design of the GT-03 offers a very futuristic look. The soft edges and flat angles offer the case the appearance of a stealth fighter. A door in the upper area hides the three external drive bays. There are two 5.25 inch bays available, as well as a 3.5 inch bay for the installation of a card reader. Tool-free mounting of the drives is a given. In the lower part of the front a red-lit 120 mm LED fan is located. Due to the fine MESH element at the bottom of the front the fan comes perfectly into play.  

The main features of the GT-03 are located in the top cover, which makes them easily accessible. Next to the I/O-panel with power- and reset-button, 2 x USB 3.0, 2 x USB 2.0 and the audio ports, the multistage 2-channel fan control is located at the right side of the top cover (as seen from the front). Per channel a 2 fans can be operated and controlled. Centered in the front part of the case top, an easily accessible docking station for 2.5 and 3.5 inch hard disks is located. A sliding cover made of acrylic ensures that the connectors are protected from dust when they are not used.

The interior of the G-03 offers space for demanding gaming systems. Two HDD-cages are available for the installation of drives. The lower cage can be equipped with up to four 3.5 inch drives; the upper cage is suited for three 2.5 inch HDD/SSD. The installation of the 3.5 inch HDD does not require tools. The optical drives are secured with practical quick fasteners. For the easy routing of cables the motherboard tray offers a variety of generous cutouts. The domed side panels of the GT-03 guarantee enough space is available at the rear side of the tray.

The ventilation system of the GT-03 is designed for high performance. In addition to the before mentioned 120 mm LED fans, another 120 mm fan is preinstalled at the rear of the case. A total of five case fans can be accommodated in the GT-03. A second 120 mm fan can be mounted behind the front cover, as well as two 120 mm models under the top cover. A generous MESH inlay in the top allows optimum air flow.

A special feature of the GT-03 is the option to install fans on top of the steel chassis under the plastic top cover. This, incompatibilities to motherboard components or CPU-coolers can be excluded. To do this, the cover can be easily pulled forward, after the case front has been removed – a very elegant and space saving solution.

The power supply is mounted at the bottom of the GT-03. Thus, it draws in cool air, reducing the noise level and the life expectancy is increased. To prevent the intake of dust particles into the PSU, an easy-to-clean dust filter is mounted under the bottom.
