We have confirmed the operation of two M.2 slots, SATA 1, SATA 2, two PCI x16 slots, CPU FAN, and Chassis FAN 1 after installing an i7-7820X and one memory stick.
The image shows the BIOS screen, and operation has been confirmed with Windows 10.

The M.2_2 slot did not recognize connected devices (M.2_1 allowed Windows 10 to boot).
Also, LAN2 could not connect to the internet (LAN1 connected successfully).
The button battery needs to be replaced.
We have not tested other connectors or functions.
A TPM module is not installed on the motherboard, but according to MSI, this motherboard supports firmware TPM.

However, enabling it is the responsibility of the purchaser.
No bent pins were visible upon inspection.
The CPU cooler is made by COOLERMASTER. The model number is unknown (likely HYPER EVO). The stud screws for mounting the CPU cooler to the motherboard will be loosely attached to the motherboard for shipping, so please tighten them fully upon receipt.
No noticeable scratches or dirt were found on the board.

Please consider the above conditions carefully before purchasing.

The product includes the motherboard, CPU cooler (with fan and mounting hardware), IO shield, manual, and original box. Since we have multiple of the same CPU cooler, the one you receive may not be identical to the one in the photo. Please understand this in advance.

To prevent product swapping, returns are not accepted.
Price negotiation is welcome.
Thank you for your consideration.
