Ultra-Small Micro ATX Chassis

The In Win BL040.FF300TB3F is a black steel Micro ATX Slim case with an 11.5 L internal volume. It ships with a bottom-mounted 300 W TFX power supply and supports Micro ATX or Mini ITX motherboards. A side window panel and four low-profile expansion slots complete the compact desktop package.

Clearance and Power Checks

Verify that your graphics card measures no more than 195 mm in length and that your CPU cooler stays within a 72 mm height limit. The included 300 W TFX unit is fixed in place, so confirm its output matches the power draw of the components you intend to install. Only low-profile add-in cards fit the four expansion slots.

Upgrade Path and Limits

This chassis replaces larger towers when desk space is at a premium and a 300 W TFX supply is sufficient. It adds hot-swap capability with two drive bays plus one external 5.25 inch bay, one external 3.5 inch bay, two internal 3.5 inch bays and one internal 2.5 inch bay. Builders who need full-height cards, higher-wattage PSUs or additional 120 mm fan mounts should consider a standard Micro ATX enclosure.

Questions about this item

Does the case ship with the 300 W TFX power supply already fitted, or do I need to buy a separate PSU?

The 300 W TFX unit is pre-installed in the bottom mount, so no additional power supply is required.

The spec lists four low-profile expansion slots — will a full-height graphics card fit?

Only low-profile cards up to 195 mm long are supported; full-height cards cannot be installed.

With a maximum CPU cooler height of 72 mm, what type of cooler should I choose?

Select a low-profile air cooler rated for 72 mm or less; tower coolers and most AIO radiators will exceed the clearance.
