The Vortex W25 will be one of the smallest and fastest workstation SFF PCs with 16 GB of GDDR5 VRAM. MSI calls it the ideal solution for high-end 3D or VR tasks as the small unit can be VESA mounted behind monitors and be disassembled rapidly without the need for tools for upgrading storage and RAM.
