Description

The COUGAR QBX redefines the possibilities of the Small Form Factor (SFF) market by balancing extreme hardware compatibility with a compact 178 x 291 x 384 mm frame. Designed for enthusiasts who refuse to compromise on performance, this chassis accommodates triple-slot GPUs up to 350mm and provides a dedicated thermal path for high-end components. Whether you are building a 4K gaming rig or a professional workstation, the QBX offers the expansion and cooling necessary to maintain peak stability in a minimal footprint.


This product is for:
- Hardcore Gamers: Those needing a portable yet powerful rig capable of housing flagship GPUs like the RTX 3080 for 4K gaming.
- Minimalist Desk Setup Enthusiasts: Users looking to maximize desk real estate without sacrificing the performance of a full-sized desktop.
- LAN Party Attendees: Gamers who require a lightweight, compact chassis that is easy to transport to events and competitions.
- Home Theater PC (HTPC) Builders: Users wanting a sleek, professional-looking case that fits into media consoles while supporting high-capacity storage for movies and games.
- Budget-Conscious SFF Builders: Enthusiasts entering the Mini-ITX world who need a versatile case that supports standard ATX power supplies to save on specialized component costs.

Detailed specifications:
- Form Factor: Mini-ITX
- Dimensions: 178 x 291 x 384 mm (7.01 x 11.46 x 15.12 inches)
- GPU Compatibility: Maximum length 350mm (Supports high-end cards like RTX 30 series)
- CPU Cooler Height: Maximum 105mm
- Power Supply Support: PS2 ATX (up to 140mm length)
- Storage Capacity: 1 x 3.5" HDD, 4 x 2.5" SSD/HDD, 1 x Slot-load ODD
- Cooling System: Up to 7 fans (Front 80mm x1, Top 120mm x2, Rear 90mm x1 pre-installed, Bottom 120mm x2, Left Side 120mm x1)
- Water Cooling Support: Left side supports 240mm or 120mm radiator with a 120mm fan
- I/O Ports: 2 x USB 3.0, HD Audio

Building in the COUGAR QBX is a streamlined experience thanks to its intelligent spatial management. The layout prioritizes airflow, featuring a unique independent power supply airflow path that prevents heat soak from the PSU affecting the CPU and GPU. The inclusion of washable dust filters at the bottom and front ensures long-term component health. Cable management is simplified by a dedicated backplane design, allowing for a clean interior even with the dense hardware configurations typical of ITX builds. The support for a slot-loading optical drive is a rare but welcome feature for users who still rely on physical media for high-fidelity audio or legacy gaming.

Compared to traditional Mini-ITX cases that often limit GPU length to 200mm or require expensive SFX power supplies, the COUGAR QBX offers significantly better value and flexibility. While competitors like the Cooler Master NR200 provide similar cooling, the QBX maintains a slimmer profile and includes support for legacy slot-load ODDs. Its ability to house a 350mm GPU makes it more future-proof than the Fractal Design Node 202, which struggles with the thermal demands of modern high-TDP graphics cards.

Q&A:
- What is the maximum GPU length for the COUGAR QBX? The case supports high-end graphics cards up to 350mm in length, making it compatible with many triple-fan RTX 30-series and 40-series cards.
- Can I use a standard ATX power supply in this case? Yes, the QBX supports PS2 ATX power supplies up to 140mm in length, though COUGAR A-series or STX-series are specifically recommended for optimal fit.
- Does the QBX support liquid cooling? Absolutely; the left side panel can accommodate a 240mm radiator (with one 120mm fan) or a standard 120mm radiator setup.
- How many storage drives can be installed? The chassis features impressive expansion for its size, supporting one 3.5-inch HDD and up to four 2.5-inch SSDs or HDDs.
- Is a fan included with the purchase? Yes, the COUGAR QBX comes with one 90mm rear exhaust fan pre-installed to assist with immediate heat dissipation.
