Installation Guide
Remove Front Panel
To remove the front panel, locate the handle at the top and bottom. Pull the handle to release the panel. The panel detaches by pulling it away from the chassis.
Diagrams illustrating pulling the top and bottom handles to release the front panel, and an exploded view showing the panel detaching.
Remove the Side Panel
First, remove the front panel. Then, open the side panels. To fully release a side panel, move it upwards. Be sure to peel off any protective film from the side panels before use.
Without removing the front panel, the side panels cannot be fully opened.
Peel off the protective film from the side panels.
Diagrams showing the side panel opening after the front panel is removed, and an illustration of peeling off the protective film from the tempered glass panel.
Motherboard Installation
Install the motherboard using the provided screws. For E-ATX motherboards, the motherboard tray can be turned 180 degrees to accommodate the larger size. Use the included tool to remove stand-off bolts if necessary.
Diagrams showing the motherboard installation area, the tool for stand-off bolts, and the 180-degree rotation of the motherboard tray for E-ATX motherboards.
PSU Installation
The PSU (Power Supply Unit) is installed on its designated tray at the bottom of the chassis. Support for ATX PSUs is provided.
Diagrams showing the PSU installation area and the PSU secured in place.
2.5" SSD / 3.5" HDD Installation
To install 2.5" SSDs or 3.5" HDDs, press the release mechanism on the removable HDD tray to open it. Insert the drive, then push the HDD tray in before closing the handle to secure it. The HDD rack position can be adjusted.
The HDD tray needs to be pushed in before closing the handle.
The HDD rack position can be adjusted.
Diagrams illustrating the process of opening the HDD tray, inserting a drive, and closing the tray. Also shows the adjustable position of the HDD rack.
2.5" SSD Installation (Alternative)
2.5" SSDs can also be installed directly onto specific mounting points within the chassis using the provided screws and anti-vibration rings. Slide the SSD into position and secure it.
Diagrams showing alternative mounting locations for 2.5" SSDs and the process of securing them with screws.
LED Control Installation
Connect the LED header to the motherboard's ADDRESS LED HEADER (+5V D GND). The LED control button on the I/O panel allows for various lighting effects. Press the 'M' button to cycle through 8 lighting effects: 1st-7th are MCU built-in lighting modes, and the 8th syncs ARGB lighting with the motherboard. To turn off the lighting, press the button for 3 seconds; press again for 3 seconds to turn it on. Press the 'C' button to control the 7 built-in static colors.
Diagrams showing the LED control button, the LED header connection to the motherboard, and the connection to the PSU.
I/O Ports Function
The front I/O panel includes: 1 x AUDIO / Microphone Combo Jack, 2 x USB 3.0 ports, and 1 x USB 3.1 Type C port (optional). Connect the corresponding headers to your motherboard. The USB 3.0 header supports a 20-pin connection. The USB 3.1 Gen.2 header is also available.
Diagrams showing the front I/O ports, the internal HD AUDIO and USB 3.0 headers, and the USB 3.1 Gen.2 header.
120 mm Fan Installation
The chassis supports various fan configurations. The removable fan tray can be reversed and offers four different installation styles. Loosen the screws on both sides to pull and release the fan tray.
Diagrams showing how to loosen screws and pull to release the fan tray. Illustrations of the four different styles (Styles 1, 2, 3 Reversed, 4 Reversed) for the reversible fan tray.
Radiator & Cooling Support
The LANCOOL II supports various radiator and fan sizes for cooling:
- Top: 120 x 120 mm, 120 x 240 mm.
- Front: 120 x 120 mm, 140 x 140 mm, 120 x 240 mm, 140 x 280 mm, 120 x 360 mm.
- Bottom: 120 x 120 mm, 120 x 240 mm, 120 x 360 mm.
To install a 360 mm radiator, remove the cover at the bottom of the front panel area.
140 x 140 mm / 140 x 280 mm radiators do not apply to the bottom position.
