Intel Desktop Board D845EPI Technical Product Specification
2.10 Mechanical Considerations
The Desktop Board D845EPI is designed to fit into either a microATX or an ATX-form-factor chassis. Figure 11 illustrates the mechanical form factor for the Desktop Board. Dimensions are given in inches [millimeters]. The outer dimensions are 9.20 inches by 8.20 inches
[233.68 millimeters by 208.28 millimeters]. Location of the I/O connectors and mounting holes are in compliance with the ATX specification.
#INTEGRATOR’S NOTE
When installing the Desktop Board in a microATX chassis, make sure that peripheral devices are installed at least 1.5 inches above the main power connector, the diskette drive connector, the IDE connector, and the DIMM sockets.

Technical Reference
2.10.1I/O Shield
The back panel I/O shield for the Desktop Board D845EPI must meet specific dimension and material requirements. Systems based on this Desktop Board need the back panel I/O shield to pass emissions (EMI) certification testing. Figure 12 shows the critical dimensions of the I/O shield. Dimensions are given in inches [millimeters], to a tolerance of ±0.020 inches
[0.508 millimeters].
The figures also indicate the position of each cutout. Additional design considerations for I/O shields relative to chassis requirements are described in the ATX specification. See Section 1.5 for information about the ATX specification.
#INTEGRATOR’S NOTE
An I/O shield compliant with the ATX chassis specification 2.03 is available from Intel.
