Case Xigmatek Osiris Mesh Case EATX 4 x 140 mm ARGB fans

This is the Xigmatek Osiris Mesh – a middle tower case with tempered glass and good airflow focus, aimed at mid-range and more serious builds, including EATX configurations. It supports a wide range of formats – from Mini ITX to Extended ATX, so you can easily plan for a larger motherboard + powerful GPU setup. The package includes 4 ARGB fans, saving you a separate investment for basic cooling and aesthetics. Maximum length for the graphics card 400 mm and cooler height up to 180 mm provide enough freedom for a serious gaming or workstation build.

What you get

The chassis is a middle tower but supports ATX, Micro ATX, Mini ITX, and Extended ATX, which is convenient if you want to upgrade to a larger motherboard in the future without changing the case. The mesh design combined with the included ARGB fans and options for additional fans at the front, top, and on the PSU shroud means serious potential for airflow, even with warmer GPU/CPU. The tempered glass allows you to showcase components and ARGB lighting without sacrificing rigidity and sound insulation like acrylic. You have 2 x 3.5" and 3 x 2.5" slots, which is more than enough for a combination of SSD for the system and several large HDDs for games or storage. On the front panel, you have USB 3.0, 2 x USB 2.0, and HD Audio – everything you need for quick access to flash drives, headphones, and peripherals.

• Support for formats Mini ITX, Micro ATX, ATX, and Extended ATX, allowing from compact to massive high-end configurations in the same chassis.
• Includes 4 ARGB fans, so right out of the box you have basic cooling and synchronizable lighting without additional purchases.
• Maximum length for the graphics card up to 400 mm, providing space for long, triple-slot GPU models without compromise.
• Support for CPU coolers up to 180 mm height, which opens up possibilities for more serious air towers.
• Rich fan options: at the front 3 x 120 mm or 3 x 140 mm, at the top 3 x 120 mm or 2 x 140 mm, at the back 1 x 120 mm or 1 x 140 mm, plus 2 x 120 mm on the PSU shroud for additional airflow to the GPU.
• Two 3.5" slots and three 2.5" slots, sufficient for combining fast SSDs and large HDDs for games, media, or backup.
• Support for power supplies up to 220 mm, allowing you to install a longer, powerful PSU without worrying about space.

Who it is suitable for

The case is suitable for gamers and enthusiasts who want an EATX or standard ATX build with good airflow and visible ARGB aesthetics, without jumping into a huge full tower. It is also suitable for heavier configurations with long graphics cards and taller air coolers. If you are looking for an ultra-compact or office-discreet case, this chassis will likely feel larger and
