⚙️ Fit Notes
- Match your original motherboard part number whenever possible
- Confirm your original board is marked WG864, 0WG864, or CN-0WG864
- Confirm your desktop is a compatible Dimension E520 / 5200 tower system
- This is a chassis-specific OEM motherboard and should not be treated as a universal ATX replacement board
- Verify the rear I/O layout, screw mounting points, power connectors, front-panel connector, SATA layout, and fan connector before ordering
- Confirm your existing CPU is compatible with the board’s Socket LGA775 processor platform
- Confirm your memory is compatible DDR2 desktop DIMM memory
- This board is not intended for Dimension E521, E510, 5150, small form factor systems, or other desktop models unless the original motherboard part number matches
- CPU, heatsink, fan shroud, memory, CMOS battery, cables, I/O hardware, and expansion cards are not included unless shown
- Some replacement installations may require BIOS setup changes or BIOS flashing depending on configuration
- Always disconnect AC power, discharge the system, and follow proper ESD safety procedures before replacing a motherboard
