Deliver Time

  • Once your order has been handed over to the carrier for delivery, you will receive a shipment notification email with an estimated delivery date. Please note that it is not possible to expedite your delivery and receive your package earlier than the scheduled delivery date. Therefore, we are unable to accept requests for expedited delivery. Our carriers are unable to provide an exact time of day for your delivery. If you ordered multiple items, you may receive separate shipments.
  • All estimates are based on business days. We only make deliveries in the specified areas of Hong Kong from Monday to Sunday except on the first two days of the Lunar New Year and when typhoon warning signal No. 8 or above or black rainstorm warning is in force.
  • All rescheduling of delivery, additional purchases, new sales memos and amendments must be made 3 days before the scheduled delivery date. Otherwise, a double delivery charge will be incurred.

  • For postal deliveries, no signature is required and order status tracking is not available.

Your Rating

Combine a GPU with your Mac mini using the DuoModo xMac mini (Intel) / eGPU Rackmount System from Sonnet. Featuring a preinstalled eGPU module, this rackmount system accepts an Intel Mac mini, available separately. Connecting to its host via the internal Thunderbolt 3 port, the mac housing provides a Thunderbolt 3, USB 3.2 Gen 2 Type-A, and two Type-C ports, while also preserving access to Mac mini ports. Plus, two M.2 NVMe SSD slots can be used to install up to 16TB of storage. A convenient internal USB also provides connectivity for a thumb drive or iLok USB key.

The included eGPU module accommodates Thunderbolt 3 graphics cards measuring up to 2.5 slots wide. Two 8-pin (6+2 pin) connectors allow for easy installation of GPUs, and the eGPU supports a total bandwidth of 2750 MB/s. A built-in 800W power supply ensures plenty of juice for graphics cards. Dual temperature-controlled cooling fans utilize variable speeds to prevent overheating. In addition to a Thunderbolt 3 and power cable, a ThunderLok 3 retainer clip is included. Please note, this system does not come with graphics cards or a Mac mini preinstalled.

Compatible with Intel Mac minis, this steel rackmount enclosure allows you to securely combine your computer with the preinstalled eGPU module.

Internal Ports
An internal USB 3.2 Gen 2 Type-A port allows you to connect a USB storage drive or an iLok USB Type-A license key. Use the internal Thunderbolt 3 port to connect the eGPU module to your Mac mini, available separately.

External Ports
Along with two ports on the rear of the eGPU module, this enclosure sports a Thunderbolt 3, USB 3.2 Gen 2 Type-A, and two USB 3.2 Gen 2 Type-C ports on the front panel. Also, it is designed to preserve access to your Mac mini ports.

Room to Flex
Install GPUs up to 2.5 slots wide. Thunderbolt-compatible cards are supported.

Quiet Operation
The dual cooling fans are rated at a max noise level of 17 dB for unobtrusive operation. A dedicated cooling fan also provides airflow to your Mac mini.

Ready When You Are
This module utilizes a built-in 800W power supply. Two 8-pin (6+2 pin) power connectors ensure graphics cards get the juice they need.

Thunderbolt 3
Thunderbolt 3 is a hardware interface that utilizes the reversible USB Type-C connector. Doubling the speed of its predecessor, Thunderbolt 3 features a maximum throughput of 40 Gb/s when used with compatible devices. The connector also transmits data via USB 3.1 at up to 10 Gb/s, and dual-bandwidth DisplayPort 1.2 allows you to connect up to two 4K displays simultaneously. Additionally, you can daisy-chain up to six devices from a single Thunderbolt 3 port.

USB 3.2 Gen 2
Doubling the speed of its predecessor, USB 3.2 Gen 2 features a maximum throughput of 10 Gb/s when used with compatible devices and is synonymous with USB 3.1 Gen 2.
