The product is great, looks good, but ... the PCIe expansion card is not present, although it is listed in the Amazon product description. The package does not have to offer such even after package label. So is to acquire the USB 3.0 adapter (installation problems) now even the acquisition of the missing PCIe card, if you (like me) do not yet have the part of the motherboard via a USB 3.0 port. Too bad!
Who needs the kit (PCIe card) must have the buy here well: Seagate FreeAgent GoFlex Desk Desktop Adapter USB 3.0 kit
