Gray market parts are items that are not authorized by the manufacturer for sale. They could be parts that were intended for sale in different countries, and often computer stores will sell you parts or computers that are gray market items, which are items that are not authorized by the manufacturer for sale. This doesn't mean that the parts are bad, they're often the same as parts that are used in non-gray market computers, but there are no warranties associated with them so you have to be careful. It's also difficult to really tell if you're getting a gray market item or a non-gray market item. So, you want to make sure when you're buying your parts or your computers you're buying them from a reputable store.
