Formula V Line Unveils Three Next-Generation PC Cases: Crystal Z7, Crystal U9 Series, and Air Power G9 Duo

December 2025 — Formula V Line announces the launch of three cutting-edge PC chassis designed for enthusiasts, builders, and gamers seeking unmatched cooling, flexible layouts, and standout style: the Crystal Z7, the Crystal U9 series, and the Air Power G9 Duo.

Crystal Z7 — Performance-Driven Mid-Tower with Extreme Cooling Flexibility

The Crystal Z7 mid-tower merges performance-oriented engineering with a sleek, premium design. Built to support EATX, BTF 2025, ATX, mATX, and ITX builds, this spacious chassis accommodates high-end hardware with room for up to eleven fans and multiple radiator configurations for optimized airflow and thermal performance.

Key highlights include:

• Angled Airflow, Optimized for GPUs – Angled fan brackets that channel cool air precisely to the GPU for enhanced thermal efficiency.
• Dual-Chamber Design – Dual-chamber design and clean cable management to keep systems tidy and airflow unobstructed.
• Dual 120mm Rear Fans – Dual 120mm rear fan configuration enhances rear heat exhaust for improved thermal efficiency.
• Spacious CPU and GPU Compatibility – Support for long graphics cards (up to 435 mm) and tall CPU coolers (175 mm).

The Crystal Z7 is available in standard and PA (Performance ARGB) versions.

Crystal U9 Series — Stylish Mid-Tower for Balanced Airflow and View

The Crystal U9 series delivers a refined aesthetic with a curved tempered glass front panel and broad compatibility for modern builds. Supporting BTF/EATX, ATX, mATX, and ITX motherboards, it offers excellent airflow with support for up to nine 120 mm fans and top-mounted 360 mm radiators.

Standout features include:

• Curved Glass Front Panel – Seamless curved tempered glass creates a refined, modern showcase design.
• Tool-Free Quick-Release Design – Removable panels enable fast installation, upgrades, and maintenance.
• Dual-Chamber PSU Design – Isolates the power supply and cables for cleaner airflow and a more organized interior.
• Large Side Ventilation Panel – Expanded side airflow openings enhance cooling efficiency for high-performance components.
• Efficient Dust Protection – Integrated dust filters help keep the system clean without restricting airflow.
• Built-In GPU Support Bracket – Improves structural stability and prevents graphics card sag.
• Large Mesh Top Panel & Enhanced Cable Channels – Optimized airflow paths and clean cable routing support better thermal performance.
• PA & SA Versions Available – Performance ARGB (PA) and Standard ARGB (SA) editions match different cooling and lighting preferences.
• High-End Hardware Support – Accommodates GPUs up to 420 mm and CPU coolers up to 182 mm for powerful builds.

The U9 series blends premium style with functional engineering to satisfy both performance-driven and showcase-oriented builds.

Air Power G9 Duo — Dual-Panel Flagship with Ultimate Flexibility

The Air Power G9 Duo represents the pinnacle of the Air series, providing dual front panels — a high-airflow mesh and a showcase-ready window — so builders can tailor their setup to performance or aesthetics.

Key innovations include:

• Dual front panel design – includes both airflow mesh and tempered glass options, allowing users to switch between cooling performance and showcase aesthetics.
• High-airflow mesh – structure maximizes fresh air intake for stable cooling under heavy system loads.
• Spacious interior – supports EATX, BTF, ATX, mATX, and ITX motherboards for flexible high-end configurations.
• Up to 12 fan mounting positions – provide extensive airflow customization for performance-focused builds.
• Built-in GPU support bracket – improves structural stability and prevents graphics card sag.
• Dual-chamber PSU layout – separates power supply and cables to enhance airflow efficiency and interior cleanliness.
• Tool-free panel design – simplifies installation, upgrades, and system maintenance.
• Comprehensive dust protection – with removable filters helps maintain long-term system cleanliness.
• PA & SA Versions Available – Available in PA (Performance ARGB) and SA (Standard ARGB) versions to match different cooling and lighting preferences.

Offered in SA (Standard ARGB) and PA (Performance ARGB) configurations, the G9 Duo satisfies a range of build preferences while delivering premium airflow and thermal performance.
