Xigmatek case Case EATX - Quantum

The Xigmatek Quantum is a middle tower case, aimed at gaming and enthusiast configurations that seek a balance between looks and practicality. It supports the full spectrum of motherboards – from Mini ITX to Extended ATX, giving you freedom for serious CPU and GPU combinations. The tempered glass showcases the entire build, while the built-in RGB and the four included fans kickstart cooling and aesthetics right out of the box. The power supply is bottom-mounted, which helps with better airflow distribution and a cleaner internal look.

What you get is a chassis prepared for heavier configurations with large motherboards and more serious water cooling. Support for radiators up to 360 mm at the front and 240 mm on top allows you to build a stable water loop for the CPU and/or an AIO solution, without wondering where to fit it. The four included fans provide basic airflow right out of the box, reducing the need for additional investments in coolers initially. The tempered glass side panel displays the RGB components and fans, so the build looks complete without additional mods. The I/O panel with USB 3.0, two USB 2.0, and HD Audio covers typical daily needs for peripherals and headphones.

• A case with a Middle Tower form factor, suitable for balanced gaming and work configurations, without taking up as much space as a full tower.
• Broad motherboard compatibility – ATX, mATX, Mini ITX, and Extended ATX, giving you freedom for upgrades and more serious platforms.
• Bottom-mounted power supply, which improves airflow and helps with better hidden cable management.
• Water cooling support with radiators 120/240 mm on top, 120/240/360 mm at the front, and 120 mm at the rear, offering plenty of options for AIO or custom loops.
• 4 fans are included, so you have ready basic cooling immediately after assembly.
• A side panel made of tempered glass, which shows off the hardware and RGB components without sacrificing durability.
• Built-in RGB lighting, which elevates the look of the entire build and allows for easy visual synchronization with other components.
• An I/O panel with 1 x USB 3.0, 2 x USB 2.0, and HD Audio for quick access to peripherals, flash drives, and headphones.
• Support for a rear fan 120 mm x 1, which ensures reliable exhaust of hot air from the case.

Who it is suitable for The Xigmatek Quantum is a good option if you are building a mid-range to high-end gaming or work machine and want space for an EATX motherboard and water cooling, without going to a huge full tower. It is suitable for RGB builds and for people who want a visually organized interior with tempered glass. If you are looking for an absolutely minimalist case without lighting or a very compact solution, this one will likely feel too large and “colorful” for you.

The strongest aspect of this case is the combination of Extended ATX support, serious water cooling options, and 4 included fans, plus a glass panel and RGB — a solid foundation for a modern, visually complete build.
