The Arena Stage 

The Kolink Unity Arena has been crafted to be the ultimate showcase for all your gaming hardware. The classic black finish serves as the perfect frame and backdrop, while the edge-to-edge tempered glass provides a panoramic view of the interior. Sporting a tool-less design, the side glass panel features a quick release at the back, enabling easy access to the chassis for installation and upgrades. 

Adding a splash of colour, the Kolink Unity Arena has four pre-installed Kolink Umbra X ARGB/PWM fans. These will illuminate your gaming PC with an endless glow, thanks to the stunning infinity mirror effect used on the fan hub and frame edges. 

Hardware Support 

The spacious interior has been intelligently designed to support a comprehensive range of hardware. As such, the Kolink Unity Arena PC Case can accommodate up to E-ATX motherboards and the eight expansion slots provide ample support for PCIe devices. What’s more, there are three additional vertical slots for vertically mounting your GPU (bracket sold separately). In total, there is 420mm clearance for graphics cards, which is more than enough room for NVIDIA RTX 40 Series GPUs!

To keep the interior clean, there is a half PSU shroud, with dedicated space for ATX PS2 power supplies a maximum of 180mm long. The included drive bay supports up to four drives. Two of the slots can hold either two 2.5" or 3.5" devices, whereas the other two only hold 2.5" SSDs. 

Extensive Cooling 

Keeping your gaming PC cool, the Kolink Unity Arena has extensive support for both air- and water-cooling hardware. The four pre-installed fans are mounted three to the side, with a reverse blade design to provide intake, and the final one is placed on the back panel for exhaust. In addition to this, there is ample ventilation across the chassis to facilitate natural airflow. 

Both the side and rear panels hold alternative fan configurations, as well as there being more support provided on the top and bottom. On the side, you can instead mount up to three 140mm fans or a 360mm radiator. Upon the rear, the other configurations are either a 140mm fan or your choice or a 120mm or 140mm radiator. The top panel offers the same support as the side, up to three 120mm or 140mm fans or 360mm radiator, whereas the bottom can hold two 120mm fans or a 240mm radiator. 

All of this support culminates in the fact you can install three radiators simultaneously, facilitating an ultra-efficient thermal solution. Finally, there is 189mm clearance for CPU coolers. 

Fully Featured I/O 

Facilitating your connectivity needs, the Kolink Unity Arena PC Case has a fully featured I/O panel on the top panel. This includes an HD audio jack, USB 3.0, USB-C, USB 2.0, and power and reset buttons. Also included is an ARGB/PWM controller with a total of six headers.
