Octagonal ATX Mid Tower for Showcase Builds

The Tower 600 Light-Year Green is an ATX mid tower case with an octagonal prism chassis designed for vertical or horizontal presentation. It targets builders who want a distinctive silhouette and broad component compatibility for high-end air or liquid-cooled systems. Buyers needing a compact footprint or a conventional rectangular layout should look elsewhere.

Top Exhaust Fans and Extensive Radiator Support

Two 140mm CT fans come pre-installed as top exhaust, and the case can hold up to 13 120mm fans or 9 140mm fans for flexible airflow planning. Radiator capacity reaches 420mm on the right side and 360mm on the left side, while CPU air coolers up to 210mm tall and power supplies up to 220mm long are supported. The internal volume prioritises cooling density over silence-focused damping.

Optional Stand and LCD Kit for Horizontal Display

A separately sold Chassis Stand Kit enables stable horizontal orientation, and an optional 3.9in LCD Display Kit can show real-time component data or custom GIFs and images. These accessories are not included and must be purchased separately to unlock the described display and orientation features. The case itself provides hidden-connector motherboard cutouts for cleaner cable routing.

Questions about this item

How do I install the 420mm radiator on the right side and which step do builders often miss?

Mount the 420mm radiator to the right panel using the included brackets, then connect the tubing before securing the panel; the step often missed is routing the tubes through the rear grommets before final tightening.

Which included components will need replacement first and when?

The two pre-installed 140mm CT fans are the only moving parts supplied; expect to replace them after several years of continuous operation when bearing noise or airflow drop becomes noticeable.

What thermal limit appears first during a long, heavy GPU and CPU load?

With a 400mm GPU and 210mm cooler installed, the 420mm right-side radiator and 360mm left-side radiator set the coolant-temperature ceiling before the nine 140mm fan limit is reached.
