Matcha Green Micro-ATX Chassis

The Thermaltake Tower 300 in Matcha Green is a Micro-ATX tower chassis built from SPCC steel with three 3mm tempered glass panels on the front, left and right. It accepts Mini-ITX and Micro-ATX motherboards and provides three internal 3.5-inch bays plus three 2.5-inch bays for storage. Four expansion slots support graphics cards up to 400mm long when no radiator is mounted on the right side.

Installation Notes

Two 140mm fans come pre-installed at the top so the first airflow path is ready immediately. The right-side bracket offers multiple 120mm and 140mm fan positions but the dense hole pattern can make screw alignment fiddly when fitting a thick radiator. Cable routing space behind the motherboard tray is adequate yet the bottom power-supply chamber limits very long units to 220mm. Front-panel connectors include one USB 3.2 Gen 2 Type-C, two USB 3.0 and an audio jack.

Sustained Load Behaviour

With a 420mm radiator on the right side the case moves large volumes of air directly across the motherboard, keeping coolant temperatures steady during extended sessions. The top exhaust fans pull heat away from the voltage-regulator area while the glass panels remain sealed, preventing recirculation. GPU thermals stay consistent because the 280mm clearance with a radiator still allows most mid-range cards to breathe. PSU intake draws cool air from the bottom vent independent of the main chamber.

Questions about this item

How can I confirm the pre-installed 140mm fans are spinning after I power on the Tower 300?

The two top-mounted 140mm fans connect to your motherboard or fan hub; once the system posts, check fan RPM in BIOS or monitoring software and verify airflow through the top mesh.

What comes in the box with the Matcha Green case and which essential parts must I purchase separately?

The chassis includes three 3mm tempered-glass panels, two pre-installed 140mm top fans, and mounting hardware; you must buy a power supply, motherboard, CPU cooler, graphics card, storage drives and any additional fans or radiators.

Which Tower 300 version should I choose if I want the Matcha Green colour with the factory-installed 140mm fans?

CA-1Y4-00SEWN-00 is the only SKU that pairs the Matcha Green finish with the two pre-installed 140mm top fans in the Tower 300 lineup.
