Micro ATX Mini Tower with 400W PSU

The Rosewill FBM-X5-400 is a compact steel and plastic chassis that includes a pre-installed 400W power supply mounted at the bottom. It accepts Micro ATX and Mini ITX motherboards and provides four expansion slots for add-in cards. A single 120mm PWM fan is fitted at the rear for immediate airflow.

Build Fit: Motherboard, Drives and Cooling

The interior holds one 3.5in drive and two 2.5in drives while leaving room for cable routing behind the motherboard tray. Front and top panels each support two 120mm or two 140mm fans, and the front can take a 240mm or 280mm radiator for liquid cooling. Dust filters cover the intake areas to reduce debris.

Capacity Limits: GPU, Cooler and PSU Length

Graphics cards up to 340mm long fit without obstruction, and CPU coolers up to 160mm tall clear the side panel. The power supply bay accommodates units up to 150mm deep, so longer ATX supplies will not install. These dimensions define the practical ceiling for high-performance parts in this chassis.

Questions about this item

Will the 400W power supply handle a high-end graphics card under sustained load?

The included 400W PSU is non-modular and CE/FCC certified. It suits mainstream builds but may limit high-end GPUs that draw more power continuously.

How loud or hot does the case get when the pre-installed 120mm rear fan runs all day?

One 120mm PWM fan is pre-installed at the rear. You can add up to two 120mm or 140mm fans at the front and two at the top to improve airflow and reduce noise under load.

What motherboard and drive sizes must I already own to fit this chassis?

The case accepts Micro ATX or Mini ITX boards, one 3.5" drive and two 2.5" drives. GPU clearance is 340mm and CPU cooler height is limited to 160mm.
