Micro-ATX case with 400W PSU

The Rosewill FBM-Z2-400 is a compact micro-ATX tower that ships with a 400W power supply already installed at the bottom. It accepts micro-ATX and mini-ITX motherboards and provides a left-side tempered glass panel for component visibility. The chassis uses steel and plastic construction with front and side mesh for airflow. Five expansion slots support full-length add-in cards up to 340mm long.

Check motherboard form factor and PSU length

Verify that your motherboard is micro-ATX or mini-ITX before ordering. The power supply mounting point allows a maximum PSU length of 150mm, so any replacement unit must fit within that limit. CPU cooler height is capped at 160mm, which affects tower cooler selection. Front I/O includes two USB 3.0 ports and audio jacks; ensure your board has matching internal headers.

Sustained cooling with top radiator support

A single 120mm rear fan comes pre-installed, while the top panel accepts radiators up to 240mm or 280mm for liquid cooling under continuous load. Additional fan mounts exist at the bottom for three 120mm units and at the top for two 140mm or three 120mm fans. Dust filters help maintain airflow over long sessions. The 400W supply delivers steady power for typical mid-range builds.

Questions about this item

Does the Rosewill FBM-Z2-400 ship with fans and a power supply, or must I buy them separately?

The case includes a pre-installed 120mm rear PWM fan and a 400W power supply mounted at the bottom. Additional fans for the top, bottom or front are not included.

Should I choose a Micro ATX or Mini ITX motherboard for this chassis?

Both Micro ATX and Mini ITX boards fit. Micro ATX uses the full expansion slot area, while Mini ITX leaves two slots unused but still supports the same GPU and cooler clearances.

What does the 340mm maximum GPU length mean when I install a graphics card?

Any graphics card up to 340mm long will fit. Measure your card from the rear bracket to the farthest edge; if it exceeds 340mm it will not clear the front panel or drive cage.
