Dell OptiPlex 3240 motherboard accessory

This genuine Dell part carries number 4075X and fits the OptiPlex 3240 all-in-one desktop. It is built for LGA 1151 socket platforms and suits repair technicians or system integrators working on that specific chassis. Buyers needing a board for a different OptiPlex model or a standard ATX case cannot use this component.

Proprietary layout matches the original chassis

The accessory follows the exact mounting pattern and connector placement Dell defined for the 3240 AIO, so it aligns with the integrated display, power delivery and I/O cut-outs without modification. Installers must verify the part number against their service tag because the form factor prevents use in generic enclosures or other Dell families.
