The Antec Flux M is a compact Micro-ATX case on Antec's F-LUX airflow platform. Six PWM fans come installed, including three 120mm reverse fans in the floor that blow straight up at the graphics card. The power supply moves to a front chamber, and the case still fits a 405mm GPU and a 360mm radiator.

About 20mm separates the bottom reverse fans from the graphics card, so they cool it directly. Air comes in through the front mesh and a large bottom mesh panel and leaves through the top vents. The bottom intake is a large mesh panel, so the fans have a wide opening to draw from.

Two 120mm ARGB PWM fans sit at the front, three 120mm PWM reverse fans at the bottom and one 120mm ARGB PWM fan at the rear. The front, top, bottom and rear mounts take up to nine 120mm fans in total.

A front-mounted PSU chamber frees internal space, and the included 13A extension cable powers high-wattage PSUs up to 160mm long. The length is measured without cables, so check the unit before you build. The unit sits at the front of the case, outside the main chamber.

The top takes a 120, 240 or 360mm radiator and the rear takes a 120mm radiator. CPU air coolers up to 175mm tall fit as well, so a compact build can use either cooling type. All of this fits in a body 365mm tall.

A built-in GPU bracket supports heavy cards, which matters for a case that holds cards up to 405mm long. The 3mm tempered glass side panel fits without tools, so the card stays in view. The case also has 5 expansion slots.

The cable space behind the motherboard measures up to 59mm at the front and 49mm at the rear. That gives the cables room in a compact body, with 5 expansion slots and 2 drive bays of each size. Good routing room matters when six fans share the case.

The front panel has power and reset buttons, one USB 3.0 port, one USB Type-C 3.2 Gen 2 port at 10Gbps and a headphone and mic jack. The front panel gets the power and reset buttons, plus the ports most builds need, within reach of the desk.
