Sonnet Technologies has announced the $999 xMac mini Server Thunderbolt 3 Edition, an updated version of its Thunderbolt-to-PCIe card expansion system and rackmount enclosure designed exclusively for Apple Mac mini computers. 

Inside its custom 1U enclosure — designed for use in 19-inch server, equipment, and portable racks — the xMac mini Server Thunderbolt 3 Edition mounts a Mac mini and connects two PCIe card slots to the computer through one of its Thunderbolt 3 ports. These slots support one full-height, full-length, single-width PCIe card, plus one full-height, half-length card (with space for a daughter card). 

One USB-A port and a power button mounted on the front panel enable operation of the system without requiring access to the back of the computer. Additional panel-mount cables (HDMI, 10 Gigabit Ethernet, and USB-A) connect ports on the computer to ports on the back of the xMac mini Server for convenient external cable connection. A power hub provides a single connection to a power outlet for the computer and the PCIe card expansion system, while a removable top lid provides access to the computer and installed cards
