Hi, the motherboard has been used, but looks new on the outside, i can vouch for the quality (motherboard doesn't have the original packaging, cd, stickers, manual),motherboard has i/o case and sata cable

Due to logistics reasons, the motherboard will not be shipped with batteries. If it is shipped with batteries, it cannot be shipped by flight. I hope you can understand
