The heart of the Echo III Desktop – the Echo III Module – is part of Sonnet’s DuoModo™ family of modular Thunderbolt expansion systems, comprising of interchangeable modules for PCIe cards and eGPU card expansion, a Mac mini mounting system (with integrated 40Gbps Thunderbolt storage dock), and desktop and rackmount enclosures so you can quickly and easily interchange modules depending on your workflow.
Choose between the Echo III Rackmount and Echo III Desktop to suit your workflow needs. The Echo III Rackmount mounts in a rack space 2U tall, and is only 16.5 inches deep, making it ideal for use in a wide range of popular mobile racks, carts, and rack cases, and in server rooms as well. The Echo III Rackmount even offers space for an optional expansion module.
