Done with CINEMA 4D R9.6 inclusive the Sky plugin that is included in the Advanced Renderer package. SolidSplinesPro was used for the cables. Modeling stuff are simple Solid Chamfer Technics smoothed afterwards with a SubDivisionSurface object. Normal 3 point light setup. CINEMA 4D internal SLA shaders were used. Compositing with some layers [Dirt and Alpha maps] in Photoshop. Original rendered image is about 5400*3500 px 300 dpi.
