Based on AMD's XConnect Technology, the Powercolor Devil Box uses Thunderbolt 3 40Gbps interface and supports PCI-Express x16 graphics cards with maximum dimensions of 310x140x50mm as well as a 375W. 

According to Powercolor, the 375W TDP is enough to power AMD Radeon R9 Fury, R9 Nano and any R9 300 series graphics card or Nvidia's GTX Titan X, GTX 980 Ti and any other Geforce 900 series graphics card. It appears that the new Pascal-based Geforce GTX 1080 and Geforce GTX 1070 graphics cards did not make it to the list but we see no reason why it should not work. 

The rest of the features include Gigabit Ethernet, four USB 3.0 and a SATA 6Gbps port, which should allow users to add a 2.5-inch HDD or SSD to the system.

Unfortunately, Powercolor's announcement did not include any details about the price or the precise availability date, but hopefully we will hear more information during Computex 2016 show.
