Compact Micro ATX tower for storage builds

The In Win EFS712.CQ450TB3 is a black Mini Tower that accepts Micro ATX motherboards and provides four expansion slots. It offers one external 5.25 inch bay, one external 3.5 inch bay, four internal 3.5 inch bays and three internal 2.5 inch bays for mixed drive configurations. Builders who need a small footprint with room for multiple hard drives will find the layout practical.

Check motherboard form factor

Verify that your board is Micro ATX because larger ATX models will not fit. The power supply cavity is limited to 130 mm so measure your unit before ordering. Graphics cards must stay within 304 mm and CPU coolers within 137 mm height. Front panel headers for two USB 2.0, two USB 3.0 and audio ports must be present on the motherboard.

Steel frame with front radiator support

The chassis is built from steel panels and includes mounting points for a front radiator up to 240 mm. Fan locations are provided at the front, rear and side for 120 mm units. Drive bays use tool-free brackets for quick swaps. The front I/O cluster puts USB and audio within easy reach on a desk.

Questions about this item

Does the EFS712.CQ450TB3 include any fans or must they be purchased separately?

The case supports up to four 120 mm fans — one front, one rear and two side positions — but no fans are included in the box.

Which drive-bay layout suits a build with several 3.5" hard drives and a 5.25" optical drive?

One external 5.25" bay, one external 3.5" bay and four internal 3.5" bays give room for an optical drive plus up to five 3.5" drives.

Will a 304 mm graphics card and a 137 mm CPU cooler fit together in this Micro ATX tower?

Yes, the chassis allows a GPU up to 304 mm long and a CPU cooler up to 137 mm tall, so both maximum-size parts can be installed simultaneously.
