This is an AKiTiO Thunder3 PCIe Box which allows usage of an internal PCI express card externally on a computer with a Thunderbolt 3 port. The PCIe expansion chassis accepts a single full height (half length) PCI express card (including two slot cards). Connects to computer using Thunderbolt 3 cable and has one additional Thunderbolt 3 port for daisy chaining additional devices.

Great for video capture, audio, storage, or networking cards.

Condition: Chassis is used, but in good working condition. There may be a few minor scuffs and scratches to the outside of the enclosure, but otherwise it is in good cosmetic condition as well (photos of actual item for sale are included in listing).

Includes: Expansion chassis, AC power adapter, Thunderbolt 3 cable, original box.



Additional information from the manufacturer: 

AKiTiO Thunder3 PCIe Box

The Thunderbolt™ 3 PCIe expansion box provides an additional PCIe slot for Thunderbolt 3 computers (e.g. laptop computers) where installing an internal expansion card is not an option and for systems where there is not enough space for more PCIe cards. The Thunderbolt 3 (USB-C) connection not only makes adding an external PCIe card easy but it also allows you to take the device with you to use on location and move it from one system to another. Installing and replacing the PCIe card is a simple matter of removing a few thumb screws and does not require any tools.
