Transplanting the tc866's motherboard on a new case?

The Aspire TC-866 desktop is designed to be installed into a =n Acer proprietary case, and it has all the diagrams for the front panel but not audio and USB 3.0 but USN 2.0. The Acer Aspire TC-866 mainboard is an Acer proprietary shape board for their distinctive desktops and it was never ever designed to be put into a different case.

To assist you here is the front panel connectors of the TC-866 from its SG, I've also included the F_USB2 (however useful that is?) as the USB 3.0 ports are all at the back and you can't have a front panel USB 3.0 connection to a case from this mainboard, there is no front panel audio connection diagrams also, you can use the back panel ports or use the Bluetooth audio. Good luck and hope this helps you out.

The Aspire TC-866 has an Intel 9th Gen CPU, measure your TC-866 internal spaces for the CPU cooler and go onto the Noctua site and see the appropriate CPU cooler that are compatible for the Intel 9th Gen CPUs and see the installation manuals for the most appropriate cooler, I'm not very familiar with your TC-866 desktop.
