3D printable functional custom decorative shroud kit for a Micro-ATX motherboard (ASRock A320M Pro4-F layout), standard manufacturing format, watertight manifold geometry optimized for FDM 3D printing. The kit consists of two separate modular pieces with a uniform wall thickness of 2.0mm and ventilation mesh cutouts for airflow. Piece 1: Rear I/O and VRM Cover. - Overall rectangular outer dimensions: 155mm length, 45mm width, 35mm height. - Design: Features a hollow chamber to bridge over the rear I/O port cluster (PS/2, DVI, HDMI, USB, Audio jacks) with an open back for port access. - VRM Safety Clearance: Incorporates a 5mm air gap above the left-side CPU VRM mosfets and solid aluminum heatsinks to allow heat dissipation. Include a top mesh surface with hexagonal 3mm ventilation grid holes for convection cooling. - Mounting: Includes two extended integrated tabs with 3.5mm inner diameter screw holes aligned with standard Micro-ATX motherboard mounting holes near the top-left corner. Piece 2: Lower Audio and Chipset/PCIe Accent Shroud. - Overall dimensions: 140mm length, 30mm width, 18mm height. - Design: A low-profile angular cosmetic cover running along the bottom-left audio trace path (ELNA Audio section) up towards the PCIe area. - Clearance: The top surface must be completely flat to clear full-length GPUs installed in the main PCIe 3.0 x16 slot. Must have a rectangular cutout to expose the "Ultra M.2" slot for SSD installation. - Style: Sci-fi cyberpunk stealth aesthetic with sharp 45-degree chamfers, clean mechanical geometric lines, and integrated 1.5mm recessed slots for potential LED strip routing. No undercuts. Референсом бери решения NZXT
