SSI-EEB Server Motherboard Clearance Model

Create a highly accurate 3D CAD model of an enterprise SSI-EEB server motherboard for a chassis clearance test layout. Generate all components as discrete solids or distinct extrusions sharing a flat base plane. Use metric millimeters (mm) exclusively. Set the coordinate origin (0, 0, 0) at the absolute bottom-left corner of the main PCB surface. 1. MAIN PCB BASE: - Draw a rectangle on the XY plane: Width (X-axis) = 330.2 mm, Height (Y-axis) = 304.8 mm. - Extrude linearly along the positive Z-axis by 2.0 mm thick. 2. STANDOFF MOUNTING HOLES (THROUGH-CUTS): Create 12 circular through-holes with a diameter of 3.5 mm cutting completely through the PCB thickness. The centerpoints (X, Y) relative to the (0,0) origin are: - Hole 1: (10.9 mm, 11.4 mm) - Hole 2: (174.8 mm, 11.4 mm) - Hole 3: (314.2 mm, 11.4 mm) - Hole 4: (10.9 mm, 78.2 mm) - Hole 5: (174.8 mm, 78.2 mm) - Hole 6: (314.2 mm, 78.2 mm) - Hole 7: (22.4 mm, 221.7 mm) - Hole 8: (174.8 mm, 221.7 mm) - Hole 9: (314.2 mm, 221.7 mm) - Hole 10: (22.4 mm, 295.4 mm) - Hole 11: (174.8 mm, 295.4 mm) - Hole 12: (314.2 mm, 295.4 mm) 3. REAR I/O SHIELD BOUNDING BOX: - Position a bounding box against the top-left edge of the PCB. - Dimensions: Length along Y-axis = 159.0 mm, Width along X-axis = 20.0 mm. - Set the top edge of this box to align flush with the top Y-edge (Y = 304.8 mm). - Extrude up on the Z-axis by 25.0 mm. 4. DUAL CPU KEEPOUT ZONES: Model two identical bounding squares on the upper half of the board to represent CPU sockets and cooler mounting areas: - CPU Socket 1 Center: (105.0 mm, 200.0 mm) - CPU Socket 2 Center: (225.0 mm, 200.0 mm) - For both sockets, draw a 100.0 mm x 100.0 mm square centered on those points. - Extrude up on the Z-axis by 6.0 mm. 5. PCI-EXPRESS SLOTS (7x BOUNDING BOXES): - The topmost PCIe slot (Slot 1) centerline sits at Y = 220.0 mm. - Model 7 parallel rectangular slots tracking downwards. Each slot is spaced exactly 20.32 mm apart center-to-center down the Y-axis. - Individual Slot Dimensions: Width along X-axis = 100.0 mm, Thickness along Y-axis = 6.5 mm. - Position the left edge of all slots starting at X = 25.0 mm. - Extrude all slots up on the Z-axis by 6.0 mm. 6. MAIN POWER CONNECTORS: - ATX 24-Pin Connector: Rectangle at the rightmost edge. Position at X = 315.0 mm, Y = 140.0 mm. Dimensions: 10.0 mm (X) x 50.0 mm (Y). Extrude Z = 12.0 mm. - Dual EPS 8-Pin Connectors: Rectangles at the top-right corner. Position at X = 290.0 mm, Y = 285.0 mm. Dimensions: 15.0 mm (X) x 25.0 mm (Y). Extrude Z = 12.0 mm. 7. COMPONENT PINS & HEADERS (FRONT PANEL & FAN PLUGS): - Model 4 localized grid clusters along the bottom edge (Y = 5.0 mm to 15.0 mm, X arrayed from 50.0 mm to 150.0 mm). - Each header block is a 2.54 mm x 20.0 mm rectangle. - Extrude up on the Z-axis by 8.5 mm to represent bare male connector pins. Ensure all geometries are clean, booleaned together correctly to the base PCB sheet, and ready for clearance modeling.
