Compact Micro ATX Tower

The Cooler Master TD300 Mesh is a Micro ATX tower built from steel, mesh, plastic and tempered glass in a black finish. It accepts Micro ATX and Mini ITX motherboards and includes a tempered glass side window. Two CF120 PWM ARGB fans come pre-installed and connect to the supplied ARGB and PWM hub for simple lighting and fan control.

Upgrade from tighter Micro ATX builds

The case supports graphics cards up to 344 mm long and CPU coolers up to 166 mm tall, giving headroom that smaller chassis often lack. Radiator mounts at the front and top accept 120, 140, 240 and 280 mm units, while the rear takes a 120 mm radiator. The removable top panel and adaptable drive cage make the jump worthwhile when you need liquid cooling or extra drives.

Straightforward assembly with a few watch points

The front fans can only be mounted behind the front plate, so plan cable routing before securing them. The bottom mounted power supply location and included dust filters on the bottom, front and top keep the interior clean. Front I/O provides two USB 3.2 Gen 1 ports, two audio jacks and the hub controls, all within easy reach.
