This is a hard disk case that holds five 3.5-inch HDDs. I bought it new and used it for two days, but the specification of "sleeping after about 8 minutes of no access" wasn't suitable for my use. Since it was used for only two days, there is almost no dust inside. There are a few scratches on the bottom (see photo). Box, instruction manual, and all accessories are included. I will attach the shipping label to the box and send it.
