Curved glass showcase and EATX support

The Formula V Line Crystal U9 PA is a mid-tower chassis built from black SPCC steel with a curved tempered glass front panel. It accepts ATX, EATX, Micro-ATX and Mini-ITX motherboards and provides seven expansion slots for full-size builds. A dual-chamber layout separates the bottom-mounted power supply from the main compartment for cleaner cable routing. Four PA120 ARGB PWM fans are pre-installed on the motherboard side and rear.

Builders needing extreme radiator length

This case suits enthusiasts who want a showcase build with a curved glass front and strong top-mounted liquid cooling support up to 360mm. It fits graphics cards up to 420mm and CPU coolers up to 182mm. Builders who need more than one 3.5-inch bay or a single 2.5-inch bay should look elsewhere. The side fan mounts are occupied by the included fans, limiting alternative side intake configurations.

Top 360mm radiator clearance

The decisive specification is the top panel radiator support limited to 360mm, which sets the maximum liquid cooling capacity for the chassis. Combined with the 420mm GPU length and 182mm CPU cooler height allowances, this figure determines whether a planned high-performance thermal solution will fit. The case measures 480 x 235 x 484mm and weighs 9.84kg.

Questions about this item

Will my existing E-ATX board and 420 mm graphics card fit inside the Crystal U9 PA?

The chassis supports E-ATX, ATX, Micro-ATX and Mini-ITX motherboards and clears graphics cards up to 420 mm long.

How can I confirm the four pre-installed PA120 ARGB PWM fans are running correctly after I build?

Connect the PWM and ARGB cables to the motherboard headers then verify fan speed and lighting control through the board's fan-tuning software or BIOS.

Does the box include a power supply or must I supply my own?

No power supply is included; the case has a bottom-mounted PSU bay so you will need to purchase a standard ATX unit separately.
