Micro ATX Case for Clean Builds

The ASUS A21/WHT// is a white Micro ATX chassis built from steel, plastic and tempered glass. It accepts Micro ATX and Mini ITX motherboards and includes hidden-connector support for BTF boards. Two 3.5-inch and one 2.5-inch internal bays handle storage, while five expansion slots cover full-length add-in cards. Front I/O supplies two USB 3.2 Gen 1 ports and dual audio jacks.

Sustained Load Cooling Behaviour

A 40-percent porous front mesh feeds up to three 120-millimetre or two 140-millimetre intake fans, matched by identical top mounts and a single 120-millimetre rear exhaust. Radiator clearance reaches 360-millimetre units at front and top, letting liquid loops dissipate heat continuously without throttling. Dust filters on bottom and top panels protect the airflow path during long sessions.

Upgrade Path from Tighter Chassis

The 33-millimetre cable-management compartment and colour-coordinated internal I/O cables replace the cramped routing found in many budget cases. Builders moving from enclosures limited to 240-millimetre radiators or shorter graphics cards gain headroom for 380-millimetre GPUs and 165-millimetre CPU coolers. The jump is worthwhile when a compact footprint must still swallow high-wattage components.

商品問答

How loud does the case get when fans are running all day?

The 40% porous front mesh balances airflow and dust filtering, so installed fans can move air at lower speeds for quieter operation.

What extra parts do I need before this case is usable?

You must supply a Micro ATX or Mini ITX motherboard, a power supply up to 210 mm long, a CPU cooler no taller than 165 mm, and your own storage drives.

Will my existing 360 mm radiator fit alongside the motherboard tray?

Yes, the case supports a 360 mm radiator in the front or top, and the 33 mm cable-management compartment behind the tray leaves room for tubing.
