Hardware Installation Preparation
Panel Removal
- Step 1-1, 1-2: Remove Side Panel.
- Step 1-1, 1-2: Remove Top Cover.
- Step 1-1, 1-2: Remove the inner side panel.
- Step 1-1, 1-2: Remove Front Panel.
These diagrams illustrate the process of preparing the case for hardware installation by sequentially removing external panels: the side panel, top cover, inner side panel, and front panel.
Component Removal
- Step 1-1, 1-2: Remove the power supply bracket.
- Step 1-1, 1-2: Remove the dust filter.
Further preparation involves removing the power supply bracket and the dust filter to allow for component installation.
Motherboard and Radiator Installation
Motherboard Installation
- Install motherboard using screws (A x8).
This section shows the installation of the motherboard onto the case standoffs using eight motherboard screws (labeled A).
Radiator Installation
- Install radiator.
The diagram demonstrates the mounting of a radiator, typically in the top or bottom positions, compatible with various fan sizes.
Power Supply Unit (PSU) Installation
PSU Rack Adjustment and Compatibility
- The PSU rack offers 4-level height adjustment.
- Compatibility notes:
- When GPU length is less than or equal to 330mm, the PSU can be installed in the Level-4 hanging position.
- When three 120mm fans are installed at the top, the PSU can be installed in the Level-2 hanging position.
- Specific PSU length limits (e.g., 14cm for 360 AIO at top) and GPU length limits (e.g., 400mm, 342-360mm, 335mm) are shown across different PSU rack levels.
- Note: Calculated GPU length includes the PCI-E bracket.
- Note: GPU length limit depends on PSU installation direction.
- Note: If a 360 AIO is installed under the top cover, a 14cm PSU is recommended for more GPU installation space.
These diagrams detail the power supply installation, including a 4-level adjustable PSU rack. They illustrate how different PSU rack positions affect the maximum supported graphics card length and PSU length. Specific scenarios are provided, such as when using shorter graphics cards or when top fans are installed. Important notes clarify length calculations and dependencies.
PSU Mounting
- Install PSU using screws (E x4).
- Note: Power plugs should be inserted into the PSU before mounting.
This step shows the physical mounting of the power supply unit into the case using four screws (labeled E), with a reminder to connect power cables to the PSU beforehand.
Graphics Card Installation
- Before installing the graphics card, connect USB, switch, and other related cables to the motherboard.
- Install the graphics card.
The process begins with connecting essential front panel cables (USB, power switch) to the motherboard. Subsequently, the graphics card is installed into the appropriate PCI-E slots.
Cooling and Compatibility
- Fan mounting positions:
- Front: 120mm x 1
- Top: 120mm x 3 or 140mm x 2
- Rear: 120mm x 1
- Bottom: 120mm x 3 or 140mm x 2
- Radiator compatibility:
- Top: 240mm, 280mm, 360mm
- Rear: 120mm
- Bottom: 240mm, 360mm
- Recommendation: Route cables behind the motherboard tray and connect them before securing fans with screws.
This section details the cooling capabilities, showing supported fan sizes (120mm, 140mm) and radiator sizes (120mm, 240mm, 280mm, 360mm) for various mounting locations (Top, Rear, Bottom). It also advises on cable management for fan installation.
