DeepCool MATREXX 40 3FS Case mATX

DeepCool MATREXX 40 3FS is a compact Mini Tower case for Micro ATX and Mini ITX configurations, aimed at budget and mid-range gaming and home builds. You get a tempered glass side panel, so the hardware doesn't stay hidden, and a relatively decent internal volume for its size. Despite the compact form factor, there is room for a graphics card up to 320 mm and a CPU cooler up to 165 mm, which opens options for more meaningful GPUs and more serious air coolers. It now comes with three included LED fans, so you have basic airflow and aesthetics right out of the box.

What you get

In the front, you have two 120 mm LED fans, plus one more 120 mm LED fan at the back, which means ready push-pull airflow without having to buy additional fans right away. The support for up to 3 x 120 mm or 2 x 140 mm fans in the front, plus up to 2 x 120/140 mm on top, allows you to upgrade the airflow if you install a hotter CPU or GPU. The support for water cooling with a radiator up to 280 mm gives you the option for AIO if you want a quieter or more efficient cooling system. For storage, you have 2 x 3.5" and 2 x 2.5" slots – enough for a combination of one large HDD for storage and several SSDs for the system and games. The PSU is bottom-mounted, supporting power supplies up to 170 mm, so standard ATX models will usually fit without drama.

• Compact Mini Tower format with support for Micro ATX and Mini ITX motherboards – ideal for smaller desks and cleaner builds.
• Side panel made of tempered glass, showcasing the internal hardware and RGB, without sacrificing strength.
• Included are 3 x 120 mm LED fans (2 in the front, 1 at the back), so you have ready airflow and basic cooling configuration.
• Large internal capacity for its class – graphics cards up to 320 mm and CPU coolers up to 165 mm, allowing for a gaming build without serious limitations.
• Option for additional fans – in the front 3 x 120 mm / 2 x 140 mm, on top 2 x 120 mm / 2 x 140 mm, providing flexibility for stronger airflow.
• Support for water cooling with a radiator up to 280 mm, if you decide to switch to AIO for lower temperatures and noise.
• Good balance between storage and size with 2 x 3.5" and 2 x 2.5" slots, suitable for a mix of HDD for volume and SSD for speed.
• Convenient front panel with 1 x USB 3.0, 2 x USB 2.0 and HD Audio for quick access to peripherals and headphones.
• Bottom-mounted power supply and support for PSU up to 170 mm, which helps for better cable and airflow management.

Who it is suitable for

This case is suitable if you want a compact Micro ATX or Mini ITX machine for gaming or work, without going into absurdly small form factors and compromising on cooling. It is a good option for budget and mid-range builds with one graphics card and standard ATX power supply. If you plan an extreme high-end setup with many hot components and multiple additional devices, a larger case with more volume may be more convenient for you.

The most sensible aspect here is the combination of compact size, glass panel, and included three LED fans, plus the space for more serious GPUs and cooling. In other words – a small case where you can comfortably build a serious yet well-cooled setup.
