DeepCool MATREXX 55 V3 ADD-RGB 3F Case

DeepCool MATREXX 55 V3 ADD-RGB 3F is a middle tower case aimed at mid-range gaming and enthusiast configurations. It supports the full range of motherboards – from Mini ITX to Extended ATX – giving you the freedom for upgrades and more serious platforms. The tempered glass side panel showcases a clean interior and the RGB lighting at the front. Right out of the box, you get 3 x 120mm ADD-RGB fans at the front, so you have basic airflow and aesthetics without having to buy additional fans immediately.

What you get is a chassis with enough space for a modern gaming build, normal cable management, and several storage drives. The four 2.5" slots are convenient for a combination of SSDs for the system and games, while the two 3.5" positions accommodate bulkier HDDs for storage, media, or backups. With up to 7 PCIe slots, you have the freedom for a larger GPU, plus additional cards if needed. The RGB button on the panel gives you direct control over the lighting of the front fans, without having to dig through software if you don’t want to. Additional fan options at the back and top allow you to further build the cooling according to your specific CPU/GPU setup.

• Case type Middle Tower, suitable for balanced gaming and work configurations with enough internal space.
• Support for motherboards ATX, Micro ATX, Mini ITX, and Extended ATX, which keeps the door open for upgrades to more serious platforms.
• Included at the front are 3 x 120mm ADD-RGB fans (CF120), providing initial airflow and RGB aesthetics right out of the box.
• Additional fan positions: at the back 1 x 120mm, at the top 2 x 120mm or 2 x 140mm, to adjust cooling according to load.
• Side panel made of tempered glass, showcasing the hardware and RGB effects without looking gaudy.
• 7 expansion slots, allowing for longer GPUs and additional cards – sound, capture, network, and more.
• Combination of storage options: 2 x 3.5" for HDD and 4 x 2.5" for SSD, convenient for a game library plus a faster system drive.
• Front I/O panel with 1 x USB 3.0, 2 x USB 2.0, HD Audio for headphones and microphone, plus RGB button for quick lighting changes.

Who is this case suitable for? For gamers and enthusiasts who want a visible build with tempered glass and factory RGB, without entering high-end chassis. It is suitable for 1080p/1440p gaming configurations, streaming, or a more serious workstation with several drives. If you are pursuing extreme water cooling or many niche PCIe expansions, you may need a larger form factor.

The combination of support for Extended ATX, glass panel, and included 3 x 120mm ADD-RGB fans makes the DeepCool MATREXX 55 V3 ADD-RGB 3F a practical choice for a modern, clean, and visually appealing build, without complicating things unnecessarily.
