This new range includes three interchangeable expansion modules, a three-slot PCIe card system, an eGPU card system, and a Mac mini mounting system with integrated 40Gbps Thunderbolt storage dock.

There are also three enclosures comprising two dual-module housings, one desktop and one rackmount, and a single-module desktop housing. Sonnet offers four preconfigured systems to simplify the order process for the most popular combinations of modules and enclosures.

The DuoModo Echo III Module, also used in Sonnet’s Echo III Desktop and Echo III Rackmount systems announced at the end of 2020, features one x16 and two x8 PCIe 3.0 slots. It accommodates full-height, full-length PCIe cards up to 12.28 inches long, connected to a computer’s Thunderbolt port via a 0.7-meter 40Gbps cable included with the kit.

The DuoModo eGPU Module supports up to full-length, full-height, 2.5 slot-width GPU cards, utilizing dual temperature-controlled, variable-speed Noctua fans for cooling the installed card reasonably quietly. Sonnet aimed here at future-proofing, equipping the module with an 800W power supply capable of supporting the future power-hungry GPU cards.

Then the DuoModo xMac mini-Module holds an Intel or M1 Mac minicomputer to enable mounting in a desktop or rackmount enclosure with open access to rear ports. The module’s built-in Thunderbolt 3 40Gbps storage dock provides users with four front panel connections, each with three 10Gbps USB ports and one Thunderbolt 3 40Gbpsport. An internal USB Type A port is provided for connection of a software license dongle, such as an iLok USB-A, or a thumb drive.
