Antec NX291 RGB (E-ATX) Mid Tower Gaming Cabinet

The Antec NX291 RGB is a premium E-ATX mid-tower gaming cabinet engineered for high-performance PC builds with advanced thermal management and RGB lighting integration. Professional system integrators, competitive gamers, and content creators rely on this chassis to house multi-GPU configurations, custom water cooling loops, and high-end power supplies up to 1000W. This cabinet solves the critical challenge of maintaining optimal airflow and component accessibility in compact form factors while delivering visually striking aesthetics for showcase builds.

Product Overview

The Antec NX291 RGB features a dual-chamber design that physically separates the PSU and storage drives from the main component area, creating independent thermal zones for superior heat dissipation. The front intake features three pre-installed 120mm RGB fans with mesh filtration, while the rear exhaust includes one 120mm fan, establishing a positive pressure airflow architecture that minimizes dust accumulation. The tempered glass side panel provides 360-degree visibility of internal components and custom loop configurations, while the integrated RGB controller supports up to 16.7 million color combinations synchronized with motherboard RGB headers via 5V ARGB protocol.

This mid-tower chassis supports E-ATX motherboards up to 272mm width, accommodates radiators up to 360mm on the front panel, and provides 7 expansion slots for multi-GPU setups. The cable management system includes a dedicated routing chamber with velcro straps, 25mm rubber grommets, and rear panel pass-throughs designed for modular PSU connections. Steel construction with reinforced frame geometry ensures structural rigidity for transporting high-value gaming rigs, while the 4mm tempered glass panel resists thermal shock from aggressive cooling solutions.

How to Use

Begin installation by removing the tempered glass panels and identifying the dual-chamber layout: the front chamber houses motherboard, RAM, and CPU cooler, while the rear chamber contains PSU and storage drives. Install your motherboard first using the provided I/O shield, ensuring the E-ATX form factor aligns with the reinforced mounting points. Connect the pre-installed RGB fans to your motherboard's 5V ARGB header or use the integrated RGB controller for standalone operation. Route all power cables through the dedicated cable management chamber using velcro straps to maintain airflow paths and prevent obstruction of intake fans.

Mount your graphics card into the topmost PCIe slot to maximize clearance for front intake fans, then install your PSU into the rear chamber ensuring the fan orientation faces downward toward the ventilation mesh. If using a front-mounted 360mm radiator, install it before mounting the motherboard to avoid component interference. Verify all fan orientations create positive pressure: three 120mm intake fans at front, one 120mm exhaust at rear. Cable management is critical in this chassis due to the compact component area, so utilize all rubber grommets and route cables behind the motherboard tray. Finally, reinstall the tempered glass panels and verify all RGB lighting responds correctly to motherboard controls before powering on.

Frequently Asked Questions

What is the maximum PSU wattage supported by the Antec NX291 RGB?

The chassis supports PSUs up to 1000W with a maximum length of 220mm. The dual-chamber design isolates the PSU compartment, allowing for efficient cable routing even with large modular units. We recommend 850W-1000W PSUs for stable operation with RTX 4090 and high-end CPU combinations. Ensure your PSU has a 80+ Gold or Platinum certification for optimal efficiency in this form factor.

Can I install a 360mm AIO liquid cooler on the front panel?

Yes, the Antec NX291 RGB is fully compatible with 360mm radiators on the front panel. The chassis includes tool-free mounting brackets specifically designed for 360mm AIO coolers. You will need to remove the three pre-installed 120mm RGB fans to install the radiator. The rear 120mm fan slot supports an additional 120mm radiator if you require a custom loop configuration. Ensure adequate clearance between the radiator and motherboard before installation.

How many storage drives can I install in the NX291 RGB?

The dedicated storage chamber in the rear supports 2x 3.5-inch HDD bays and 2x 2.5-inch SSD slots, totaling 4 storage devices. The 3.5-inch bays are mounted on a removable cage that can be repositioned or removed entirely if you prefer additional cable routing space. The 2.5-inch slots are mounted directly to the chamber wall with rubber isolation to reduce vibration noise during operation.

Does the Antec NX291 RGB support dual GPU configurations?

Yes, the chassis features 7 PCIe expansion slots specifically designed for multi-GPU setups. Dual RTX 4090 graphics cards can be installed with proper spacing and airflow management. However, you must ensure your motherboard supports dual-GPU configurations and your PSU has sufficient power connectors. The front intake fans may require repositioning or removal to accommodate dual-slot GPU coolers. We recommend consulting your GPU manufacturer's spacing requirements before installation.
