The glass panels meet at the corner with no pillar in the way, giving a clear view of the motherboard and the graphics card. The side glass is 4mm tempered glass. An inclined power supply shroud with an ARGB lighting strip adds another light line along the bottom of the view.

The top, the bottom and the right side use honeycomb mesh so air can pass through while dust is held back. That mesh pairs with the three reverse fans on the right side, which pull air in through the side of the case. The arrows in this graphic mark the intake and exhaust paths.

Three 120mm PWM ARGB reverse fans sit on the right side and one 120mm PWM ARGB fan sits at the rear. A built-in controller handles the fan speed and the lighting effects, which can also be switched with the LED control button. That means nothing extra to buy before you power on.

The top mount takes 120, 140, 240, 280 or 360mm radiators, and the side mount takes 120 or 240mm. Antec states that a 360mm top radiator and a 240mm side radiator fit at the same time. The rear adds one more 120mm mount for an exhaust fan or radiator.

The case supports 8 x 120mm fans at the same time. The top takes 3 x 120mm or 2 x 140mm, the side takes 3 x 120mm, the bottom takes 1 x 120mm once the HDD cage is out, and the rear takes 1 x 120mm. This chart lays the fan and radiator positions side by side.

The front panel has a Power button, an LED Control Button, a USB 3.0 port, a Type-C 3.2 Gen 2 port and a headphone and mic combo jack. Antec labels the Type-C port as the high-speed one. Only one USB 3.0 port is fitted, so a hub or a motherboard header may be needed for more.

Magnetic filters cover the top, the bottom and the right side, and another flat filter sits at the bottom. Together that makes 4 dust filters for the three mesh sides. The panels exploded in this view show where each filter lies, and the magnets make them easy to lift off and rinse.
