PC Case Thermaltake View 91 TG RGB Ultra Tower Black

The Thermaltake View 91 TG RGB Ultra Tower Black is an XL-ATX super tower chassis designed for high-performance and liquid-cooled PC builds. It features three 5 mm tempered glass panels (front and both sides) with swing-door hinges, a spacious interior that supports XL-ATX motherboards and large cooling configurations, and four preinstalled 140 mm Riing PLUS RGB fans. The front panel includes a USB 3.1 Type-C port and the chassis is Tt LCS Certified for compatibility with advanced liquid cooling setups.

Advantages

The case offers extensive cooling flexibility with support for multiple radiator placements including vertical radiator view (VRV) options and compatibility with up to triple 480 mm DIY radiators or up to 360 mm AIO solutions. Three 5 mm tempered glass panels provide durable component visibility while hinged swing doors allow easy access. Four preinstalled 140 mm Riing PLUS RGB fans deliver customizable lighting and PWM-controlled airflow, and magnetic dust filters on top, front and bottom simplify maintenance. The integrated riser GPU support bracket enables vertical GPU layouts and helps prevent card sag.

Suitable for

• High-end gaming rigs with multiple GPUs
• Custom water-cooling loops and enthusiast liquid cooling builds
• Workstation-class builds requiring large motherboards (XL-ATX) and extensive storage
• Showcase systems where component visibility and RGB lighting are desired

How to use

Install the motherboard and power supply according to the standard motherboard standoffs and PSU mounting points. Use the swing-open tempered glass panels for easy access during component installation and cable routing. Mount radiators and fans in the supported locations — front, top, bottom, and the vertical radiator position — following radiator size limits. If using a vertical GPU layout, attach the included riser GPU support bracket and, if needed, use the optional Thermaltake TT Premium PCI‑E extender (sold separately) in appropriate length. Connect the front USB Type-C to a compatible motherboard header to enable USB 3.1 functionality.

Recommendations

For optimal cooling and component longevity, combine the four preinstalled 140 mm Riing PLUS RGB fans with additional intake/exhaust fans or compatible radiators according to your loop requirements, and use the magnetic dust filters to reduce dust buildup. When installing heavy GPUs, use the riser support bracket to prevent sag and to reduce strain on motherboard PCI‑E slots.
