Sonnet Echo Express II Thunderbolt Expansion Chassis for PCIe Cards

The Sonnet Echo Express II Thunderbolt Expansion Chassis for PCIe Cards enables you to connect one or two high-performance PCIe 2.0 cards (sold separately) to any computer with a Thunderbolt port. Imagine using full-size professional video capture, audio interface, 8Gb Fibre Channel, 10 Gigabit Ethernet and RAID controller cards with your iMac, Mac mini, MacBook Air or MacBook Pro computer.

The chassis includes a built-in 100W power supply and three variable speed fans to quietly keep cards cool, only speeding up as needed to cool the hottest cards. Two Thunderbolt ports support daisy chaining of up to six devices to a single port on your computer.
