I'm with batuchka. "Once you know, you Newegg".
Newegg does not warranty the products they sell. They offer a return service that is normally 30 days. For the holiday season, they've doubled that to 60 days. If a product you purchase fails within 60 days of the purchase date, you can return it to Newegg for a replacement (see specific return policies). Beyond 60 days, but within the manufacter's warranty period, you'll need to contact the manufacturer for repair/replacement.
Yes. It looks like that motherboard comes with two SATA cables.
