Add four external I/O expansion card slots to a desktop or laptop computer system.'s innovative PCI/PCI Express Expansion Chassis provides a quick and simple solution to I/O expandability on almost any PCI Express (PCIe) enabled system. Adding external PCI and PCIe slots to a server/workstation or laptop, this cost-effective and time-saving method of simply adding additional PCI/PCIe cards to a server/workstation or providing a platform to be able to swap PCI/PCIe add-in cards between a mobile and desktop setup is the optimal method of maximizing the I/O capabilities of new or existing systems.
The external expansion chassis adds two full length (38cm) PCI slots (32-bit/33MHz) as well as two PCIe x1 (single lane) slots to the host computer system, through a single PCI Express connection. Providing total bandwidth of up to 250MBps from the x1 PCIe host controller card, which allows the host computer to function as though the cards in the expansion chassis were connected directly to the motherboard.
For mobile applications, the Expansion Chassis can be connected to an ExpressCard enabled laptop using's ExpressCard connection cable (EC2PCI), which adds the same functionality offered by the Expansion Chassis to a laptop. This eliminates the expense and need of having to purchase different card adapters for the laptop. The Expansion Chassis is a dependable I/O expansion solution.

Rated 5 out of 5 by from it does not work We bought this to be able to use 2 PCI boards we have but after we connected everything as indicated in the manual Windows will still not see those boards even if we installed those boards inside the PC.

Rated 5 out of 5 by from Works well. Needed to dig online for help. This worked first try with my National Instruments PCI-GPIB card but the NI PCI-MXI-2 card required a lot of research to get working. The key was to turn off PCIe power management in BIOS. The PCIe interface card would go into low power mode and I would loose contact with the PCI card in the extender box. I also set PCIe Native Control to disable ( in Windows, as Admin, RUN -> bcdedit /set pciexpress disable ).
