Pro Rackmount Enclosure and PCIe Card Expansion for Mac Mini (2024+)

xMac mini (2024+)/Echo III

2U Rackmount Enclosure with Modular 3-slot Thunderbolt to PCIe Expansion

Maximize Your Mac mini Workflow – Connect Three PCIe Cards

The latest Mac mini delivers exceptional processing power, rivaling systems many times its size and cost. Yet in professional environments, raw performance alone isn’t enough — workflows often require secure rack mounting and expanded connectivity beyond what the Mac mini provides out of the box.

xMac mini (2024+)/Echo III solves this challenge, seamlessly integrating one or two Mac minis (sold separately) into a rugged, compact 2U steel rackmount enclosure that houses a dedicated computer mounting module alongside a 3-slot Thunderbolt™ to PCIe card expansion module, delivering the connectivity, flexibility, and reliability demanded by today’s most intensive audio, video, and broadcast production workflows.

Control and Connect – Easy Access to Mac minis and PCIe Card Expansion Module

xMac mini (2024+) keeps your Mac minis safely tucked away while providing easy-to-use power buttons for each one — so you can turn them on with just a press. Access is provided to the front ports on the mini mounted in front. A USB-C port provides a connection to the mini mounted in the rear, while a cable passthrough on the front panel enables connection of front computer’s USB connectors to the rear of the rack. The computer mounting and Echo III modules are secured with two rear panel thumbscrews each, enabling you to easily pull out and access the modules and installed computers and PCIe cards through the front of the enclosure. The xMac mini (2024+)/Echo III design enables you to connect and disconnect cables without needing to remove the computers from the module.

Echo III Expansion Module

Echo III is a 3-slot Thunderbolt to PCIe expansion module designed for high-performance PCIe card connectivity. From low-profile, half-length to full-height, full-length in size, Echo III Module supports every Thunderbolt-compatible, non-GPU PCIe card available. For a list of supported PCIe cards refer to Sonnet’s PCIe Compatibility Chart. The module features 40 Gbps Thunderbolt interface, a powerful 400W power supply, ultra-quiet Noctua fans (rated at 17 dBA), and a rugged aluminum enclosure for durable, secure protection.

Well Ventilated – Supports the Mac mini Thermal Design

xMac mini (2024+) enclosure system secures your Mac minis without trapping them in recirculating hot rack air, supporting their thermal design to keep them as cool in a rack as out on a desk. Ventilation holes on the xMac mini module’s front panel plus enclosed chambers beneath the computers ensures their ability to draw in cool air through their bases, while a completely open back enable them to expel warm air out the back unimpeded.

SSD Space – Secure Two Thunderbolt or USB SSDs Beneath the Mac minis

Space is provided beneath the computers to store two Thunderbolt or USB SSDs (sold separately) at maximum size of 3.2 inches wide by 0.75 inch tall. The space is also suitable for other thin, bus-powered devices.
