Swap to Suit Your Aesthetic 

The Kolink Observatory Duo ARGB Mid-Tower PC Case has been crafted to merge form and function. This chassis sports the classic combination of tinted tempered glass panelling and a matte black finish on the metal frame. Even better, the tempered glass panel is hinged, to allow you easier access to the interior, and held in place with magnets, for a clean aesthetic. For the front panel, you have a choice between two styles. Included within the scope of delivery are two front panels, one mesh and one tempered glass. Each can be easily installed or replaced, to suit your aesthetic or airflow needs.


Duo Cooling 

Enjoy extensive support for both air and water-cooling, with the Kolink Observatory Duo. There are four Kolink Umbra S ARGB/PWM 120mm fans pre-installed across the chassis, with three mounted on the front and the last upon the rear panel. With their adjustable fan speeds and vibrant ARGB lighting, these fans are cool in more ways than one!

Alternatively, there are additional fan mounting options available. Upon the front, there is support for three 120mm or two 140mm fans, which could also be used for radiators up to 360mm. The top panel has brackets for two fans, either 140mm or 120mm. In lieu of this, the space holds a radiator up to 280mm. Upon the rear panel, there is space for either a singular 120mm fan or radiator. Additionally, the PSU shroud can host two 120mm fans, to enhance the hexagonal cut-out ventilation integrated within its design. This shroud can accommodate power supplies up to 180mm long.

Thanks to the spacious design, the Kolink Observatory Duo can support dual-radiator water-cooling systems, and CPU coolers up to 170mm in height.  

Hardware Showcase 

The Kolink Observatory Duo utilises an expertly curated design that optimises hardware installation. This mid-tower case can support multiple motherboard form factors, including Mini-ITX, Micro-ATX, ATX, and E-ATX. There are seven PCIe expansion slots upon the back panel, three of which have screws. GPU clearance depends on your fan configuration. If you have fans installed on the front panel, then there is up to 335mm clearance for your graphics card. Whereas, if there are no fans on the front panel, then this space increases to 360mm.

For storage, you can install up to four drives within the Kolink Observatory Duo. There are two toolless drives, which accommodate either 2.5" SSDs or 2.5" HDDs. Upon the back of the motherboard tray are two removable SSD trays, which both support 2.5" drives.


Finishing Touches

Optimising connectivity and cable management, the Kolink Observatory Duo has a side-mounted I/O panel. It features two USB 3.1 and one USB 2.0 ports, along with an HD audio jack and power buttons.


Included with the Kolink Observatory Duo is a Kolink Umbra Core ARGB Controller. This is utilised to control the fan speeds and lighting effects on the pre-installed Umbra fans. Additionally, it offers support for more ARGB or PWM devices, as well as a singular hub for control. Create stunning light displays to perfect your gaming PC’s aesthetic!
