DarkFlash HM1 computer case
DarkFlash HM1 is a midi tower computer case that supports ATX, M-ATX and ITX format motherboards, while offering up to seven 120 mm fan slots and the ability to mount up to 360 mm of water cooling on top of the case. The internal space allows for the installation of graphics cards up to 380 mm in length and CPU coolers up to 175 mm in height. A side panel of curved tempered glass with anti-reflective coating provides a clear view of components, while the modular design and hidden cable routing system facilitate neat installation. The front features high-speed USB 3.0 and USB-C connectors, which translates into convenient support for external devices.
Efficient ventilation and support for water cooling
The HM1 chassis supports the installation of up to seven 120mm fans, which translates into efficient cooling even under heavy load. Three fans each can be mounted at the front and bottom, and one (120 or 140 mm) at the rear. The top panel supports water cooling up to 360 mm. This configuration keeps the temperature inside the case stable and minimizes noise.
Thoughtful component layout
The HM1 has been designed to ensure maximum compatibility and easy installation of components. It supports ATX, M-ATX and ITX format motherboards. Inside, space is provided for three HDDs, mounted in the bottom compartment. The motherboard is installed at the rear, allowing for more orderly cable routing and better airflow.
Built-in ports
On the front panel, the user has two USB 3.0 ports, a USB-C connector, two audio connectors and a power button. Such a setup makes it easy to quickly connect external devices and operate the hardware.
Refined design
The case features a one-piece curved tempered glass panel with high transparency. As a result, the computer's interior remains clearly visible - the manufacturer used nano-AR coating, which reduces reflections to just 3%. The magnetic top panel can be easily removed, making it easy to install fans and clean the case. Modular cable design and a hidden tool compartment make assembling the computer not only convenient, but also aesthetically pleasing.

How to use
Install an ATX motherboard and a standard ATX power supply according to the case standoffs and PSU mount. Route power and data cables through the provided cable routing paths and grommets to maintain tidy internal layout and optimal airflow. Mount storage drives and expansion cards in the available bays and slots, and install case fans or radiators at the specified front and rear ventilation points depending on your chosen cooling configuration. Ensure all components are secured before powering up the system.
Recommendations
For effective cooling, keep front and rear airflow unobstructed by routing cables behind the motherboard tray and selecting appropriately sized fans or radiators compatible with the case mounting points. Verify motherboard standoff positions and PSU orientation during assembly to ensure correct fitment and ventilation.
