The fractal define R4 would be my favourite case. 1.5 inches of space in the back for cabling, soild side panels, great gromments, my ideal IO layout, and that nothing feels cheap.
the other case one would be the nanoxia ds1, but then its not avaliable here. only problem i find in that case is not exactly as much cabling space as the R4 contains. other than that, it would be perfect
