Full-view mid-tower case with 270° glass

The Antec C3 ARGB is a mid-tower ATX chassis built around seamless tempered glass on the front and side panels. It accepts Micro ATX, ATX and ITX motherboards and comes with four pre-installed 120mm PWM ARGB fans, including three reverse-mounted units on the right side for direct intake. A built-in controller manages both lighting and fan speed.

Check motherboard form factor and drive needs

Verify that your board is Micro ATX, ATX or ITX before ordering. The case provides one internal 3.5-inch bay and three 2.5-inch bays, so plan storage accordingly. Seven expansion slots are available for full-length graphics cards up to 415mm. The removable hard-drive cage can be taken out to fit an extra 120mm fan at the bottom.

Sustained airflow with dual-radiator support

Honeycomb mesh on the top, bottom and right side feeds the four ARGB fans for continuous airflow under load. The top panel accommodates radiators up to 360mm while the side supports up to 240mm, allowing simultaneous liquid-cooling loops. Maximum CPU cooler height is 160mm and power supplies up to 195mm fit behind the inclined shroud.

Questions about this item

What comes in the box and do I need to buy any fans separately?

The case ships with four pre-installed 120 mm ARGB PWM fans — three reverse fans on the side panel and one at the rear — plus a built-in ARGB and PWM controller, so no additional fans are required for basic operation.

Which motherboard form factors fit and how much radiator space is there?

Micro-ATX, ATX and ITX boards are supported; the top mounts radiators up to 360 mm and the side up to 240 mm, allowing a 360 mm top and 240 mm side radiator simultaneously.

What does the 415 mm GPU clearance mean for my graphics card choice?

Any graphics card up to 415 mm long will fit, covering most current triple-fan models while leaving room for cable routing behind the inclined PSU shroud.
