PC Case Kolink OBSERVATORY MX Midi Tower Black

The Kolink OBSERVATORY MX Midi Tower Black is a mid-tower PC case designed to balance compact dimensions with component compatibility and airflow. With a tempered glass side window and steel construction, the chassis measures 200 mm (W) x 350 mm (D) x 440 mm (H) and weighs 5.6 kg. It supports ATX, Micro-ATX and Mini-ITX motherboards, accepts ATX power supplies, and provides multiple drive mounting options for both 2.5" SSDs and 3.5" HDDs.

Advantages

The case combines a tempered glass side panel and mesh front for a mix of visibility and ventilation, while its compact Midi Tower footprint preserves internal space for components. Two front 140 mm fans are pre-installed to promote front-to-back airflow; additional fan and radiator mounting locations allow flexible cooling configurations. Tool-compatible storage bays for 2.5" and 3.5" drives and a dedicated PSU shroud help organise the build and separate heat sources.

Suitable for

• Building a compact ATX, Micro-ATX or Mini-ITX desktop PC
• Gaming systems requiring improved airflow with front mesh intake
• Systems that use a mix of 2.5" SSDs and 3.5" HDDs
• Air-cooled or liquid-cooled setups with support for multiple fan/radiator layouts

How to use

Install a compatible ATX, Micro-ATX or Mini-ITX motherboard onto the standoffs, route power and data cables through the available openings and place the power supply into the shroud. Mount storage drives into the designated 2.5" or 3.5" bays and secure expansion cards in the rear slots. Use the pre-installed front fans for intake and configure additional fans or radiators on the front, top and rear mounts according to cooling needs. Connect front-panel USB and audio to the motherboard headers and, if available, attach ARGB or fan control headers to the 5V 3-pin connector for unified fan control.

Recommendations

For optimal airflow, use the mesh front with the pre-installed 140 mm fans as intake and configure rear/top fans as exhaust. When installing a longer GPU or larger CPU cooler, confirm available clearance (GPU up to ~330 mm, CPU cooler up to 160 mm) and plan cable routing to maintain unobstructed airflow pathways.
