Sonnet Echo III rack mount

Connect three full-length PCIe cards to computers with Thunderbolt 3 ports. For creative professionals using the latest portable, mini-desktop, and all-in-one computers in their workflows, built-in processing power alone isn't enough to get the job done. While these computers feature high-performance Thunderbolt 3 ports to support peripherals, what they lack are PCIe expansion slots for installing specialty cards that add the video and audio inputs you need, transcode data, and connect to high-speed shared storage and networks . Sonnet has a solution, the Echo III Desktop – a professional Thunderbolt 3 to PCIe card expansion system that allows you to connect three (up to) full-length (12.28” long) PCIe cards simultaneously via a single cable.
