The thing here is that you if you like the aesthetic. Performance wise it is a sub-par case compared to other decent cases in both thermals and in noise levels, however unless you're a super-enthusiast about either of the two it won't matter as much. It has good build quality so that's a plus.
It is a good case for both orientations, which is rare for most gaming-level towers, and it has a built in RGB controller. However it only comes with 1 pre-installed fan, meaning you're going to want at least 1 more fan for an intake (I believe the pre-installed is an exhaust).
If you like how it looks then go for it. If you care more about maximum possible thermal and noise performance, you're going to want to look elsewhere.
EDIT: Take a look at Tomshardware's review of the case, I think this will help you decide whether or not you want it.
