Thermaltake Tower 300 Micro-ATX Case CA-1Y4-00S1WN-00

Tower 300 Micro-ATX Chassis

The Tower 300 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 boards at 6.7 by 6.7 inches and Micro-ATX boards at 9.6 by 9.6 inches. The power supply mounts at the bottom and the case ships without one. Three internal 3.5 inch bays and three 2.5 inch bays provide storage flexibility for builders who want a compact vertical layout.

Sustained Thermal Behaviour

The chassis supports a 420mm radiator and offers extensive fan mounting options across top, rear, side and bottom locations. Pre-installed 140mm CT fans at the top establish a baseline airflow path that can be expanded with 120mm, 140mm, 180mm, 200mm, 220mm, 250mm or 360mm configurations. Side dust filters help maintain intake cleanliness during long sessions, while the vertical orientation encourages natural convection alongside forced airflow for steady component temperatures under load.

Build Quality and Daily Connectivity

SPCC construction and three thick glass panels give the enclosure a rigid feel and clear visibility of internal hardware. The front I/O cluster delivers USB 3.2 Gen 2 Type-C, two USB 3.0 ports and HD audio for quick peripheral access. Four expansion slots accommodate full-length add-in cards, and the optional chassis stand kit or LCD kit enables horizontal display if desk space demands it. Side-mounted dust filters are removable for routine cleaning without tools.
