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.

Questions about this item

How loud or hot does the Tower 300 get when the two pre-installed 140 mm fans run all day?

The case ships with two 140 mm CT fans at the top; they move air through the tempered-glass front and side panels while the side-mounted dust filters keep intake paths clean, so sustained loads stay cool without excessive noise.

Which components must I already own before the Tower 300 can function as a complete PC?

You need a Mini-ITX or Micro-ATX motherboard, a bottom-mounted power supply, CPU cooler and graphics card that fit the internal clearances, plus storage drives for the three 3.5" and three 2.5" bays.

Will my existing 360 mm radiator and 3.5" hard drives fit alongside the Tower 300's internal layout?

The chassis supports radiators up to 420 mm and provides three internal 3.5" drive bays, so a 360 mm unit and standard 3.5" drives install together without conflict.
