We understand you are looking for a Half Mini Card to PCIe adapter for your Intel® Dual Band Wireless-AC 7260 (HMC). The adapter was originally preinstalled into a defective motherboard, which you have replaced for a different model, and this new board does not have an HMC port.
Unfortunately we will be unable to recommend a Mini PCIe to PCIe adapter for you, as this products are not manufactured by Intel® and have not been tested for performance nor functionality by us. While you may be able to find one that works, we cannot guarantee this setup and it will not be supported.
Our recommendation for this type of application is to purchase an Intel® Dual Band Wireless-AC 7260 + Bluetooth* for Desktop or another similar adapter originally intended for PCIe installation, in order to avoid possible compatibility issues or feature limitations.
