Compact Mid Tower for Versatile Builds

The Thermaltake TR300 Snow is an ATX mid tower case built on a compact footprint. It supports Mini ITX, Micro ATX and ATX motherboards while keeping desk space in check. A 3 mm tempered glass side panel shows the interior and the chassis includes a single 120 mm PWM rear fan running at 1400 rpm.

Thermals Noise and Power Headroom

The pre-installed rear fan operates at 23.2 dBA, providing a quiet baseline for typical workloads. Up to eight 120 mm fans can be added across front, top, rear and bottom mounts, with top support for 360 mm, 280 mm, 240 mm or 120 mm radiators and a rear 120 mm radiator option. The PSU bracket adjusts in four positions to balance cable routing and airflow.

Upgrade Path From Smaller Chassis

Builders moving from Mini ITX or space-constrained cases gain 410 mm GPU clearance and 165 mm CPU cooler height, plus 260 mm PSU depth when the graphics card is 325 mm or shorter. Three 3.5-inch and three 2.5-inch drive bays add storage flexibility over tighter layouts, while front USB 3.1 Gen 2 Type-C, two USB 3.0 ports and HD audio modernise connectivity.

Questions about this item

How do I install the PSU in the front bracket and what step do builders often miss?

Mount the PSU on the four-position front bracket and choose the height that matches your GPU length; the step often missed is sliding the bracket to the 160mm PSU position when the graphics card exceeds 325mm, otherwise the card hits the power supply.

What maintenance will the pre-installed 120mm PWM fan need later?

The 1400rpm rear fan runs at 23.2 dBA; plan to clean dust from its blades every few months and replace the unit if bearing noise rises, using any standard 120 x 120 x 25 mm PWM replacement.

What thermal limit appears first when the top 360mm radiator runs under sustained load?

The top panel supports one 360mm AIO, but the 165mm CPU cooler height clearance and the 260mm PSU length limit (160mm when GPU > 325mm) restrict airflow space, so radiator thickness and fan speed become the limiting factors before coolant temperature stabilises.
