BitFenix Shinobi or Fractal Design R4

Hey guys,

I'm looking to buy a new case, I have narrowed it down to these two based on features size and design. The prices im looking at are 

BitFenix Shinobi = £59.90

Fractal Design R4 = £77.98


Just wondering what you guys would recomend based on these price points and reasons why. 


If you are on a budget get the shinobi if it will help you get better hardware in your build otherwise the R4 is a better case but costs more.  The fractal define R4 windowed is my favorite case if that helps.

Cheers for the input, based on the fact that its only £18 more I think it my be the better option.
