Corsair FRAME 4000D RS Modular Mid-Tower PC Case Black - CC-9011312-WW

The Corsair FRAME 4000D RS Modular is a middle tower case aimed at serious gaming and enthusiast builds, where you want both powerful hardware and a clean interior. It supports a wide range of formats – from Mini ITX to Extended ATX and BTF, giving you freedom for upgrades and larger boards. The side panel made of tempered glass showcases the entire build without feeling cheap or fragile. The space for a graphics card up to 420 mm and a CPU cooler up to 170 mm allows you to consider real high-end hardware, rather than compromises.

What you get is a seriously flexible chassis with many options for airflow and cable management, without being tied to included fans that you might not like. With the option for up to 3x 120mm or 2x 140mm at the front, 3x 120mm on top, as well as side and bottom mounting, you can build a classic front-to-back configuration or a more modern side-intake for lower GPU temperatures. 7+3 expansion slots provide room for vertical graphics card mounting or additional cards, without sacrificing standard positions. With a total of 2 x 3.5" and 4 x 2.5" bays, you can comfortably combine a large HDD for storage with several SSDs for the OS, games, and work. Power supplies up to 225 mm allow you to install a more serious PSU without wondering if it will fit with the cables.

• Case with middle tower form factor supporting ATX, mATX, Mini ITX, Extended ATX, and BTF, which provides freedom for various builds – from compact to more serious workstation configurations.
• Side panel made of tempered glass, which showcases the components and RGB, but is also more durable than ordinary acrylic glass.
• Rich fan options: at the front 3x 120mm, 2x 140mm, or 2x 200mm, on top 3x 120mm or 2x 140mm, on the side 3x 120mm or 2x 140mm, at the bottom 2x 120mm, and at the rear 1x 120mm or 1x 140mm, allowing you to adjust the airflow according to the hardware and noise.
• The absence of included fans (no fans in the package) gives you the freedom to choose exactly the ones you want in terms of size, color, and RPM curve, without paying for something you won't use.
• 7+3 expansion slots allow standard horizontal card mounting plus additional positions for a vertical GPU or other expansions.
• Storage flexibility with 2 x 3.5" and 4 x 2.5" bays – enough for a combination of large HDDs for archiving and several fast SSDs for games and applications.
• Front panel with modern I/O: 1x USB 3.2 Gen 2 Type-C, 2x USB 3.2 Gen 1 Type-A, and audio in/out, so you can use fast flash drives, external SSDs, and headphones without reaching for the rear panel.
• Compatibility with CPU coolers up to 170 mm and graphics cards up to 420 mm, which opens the door for serious air coolers and long high-end GPUs without wondering if they will fit.
• Support for power supply units up to 225 mm, which is convenient if you want a more powerful PSU with modular cables and a deeper chassis.

This case is suitable if you are planning a gaming or enthusiast build with upgrade potential and want to choose your fans and cooling yourself. The supported formats, graphics card length, and storage space make it a good base for heavier GPUs + many SSDs. If you are looking for something super compact or with ready-made cooling and fans included, you will need to invest separately here.

The strongest aspect of the Corsair FRAME 4000D RS Modular is the combination of a flexible internal layout, serious airflow capabilities, and modern I/O, without locking you into a pre-set configuration. You get a platform on which you can build exactly the kind of build you need – now and for future upgrades.
