Walnut wood front panel and silent build

The Antec Flux SE Silent PC Case uses a walnut wood front panel combined with steel and plastic construction to deliver a distinctive look. Sound-dampening foam on both side panels reduces operating noise for a quieter computing experience. It supports ATX, E-ATX, Micro ATX and ITX motherboards in a mid-tower layout.

Radiator limits and fan capacity

Radiator support reaches 420 mm at the front, 360 mm at the top and 140 mm at the rear, with simultaneous front 420 mm and top 280 mm installation possible. The case accommodates up to nine fans and ships with five PWM fans pre-installed at front, middle and rear positions. Fan mounts accept 120 mm or 140 mm units throughout.

Maximum graphics card length

The chassis clears graphics cards up to 408 mm long, CPU coolers up to 180 mm tall and power supplies up to 235 mm deep. Two internal 3.5 inch and two 2.5 inch drive bays provide storage flexibility. Seven expansion slots and a USB Type-C front port complete the connectivity.

Questions about this item

Should I pick the front 420mm radiator option or the top 360mm option for liquid cooling?

The case supports both layouts simultaneously. You can run a 420mm radiator at the front together with a 280mm at the top, or a 360mm at the front with another 360mm at the top.

What does the 408mm maximum GPU length mean when I install a graphics card?

Any graphics card up to 408mm long will fit, leaving room for front-mounted radiators or fans without interference.

How does the USB Type-C port on the front panel connect to my motherboard?

The front USB Type-C port uses an internal header on the motherboard; it provides standard USB 3.1 Gen 1 speeds when connected to a compatible header.
