blackhawks2013 :
Mid size case
I heard that the build quality on the 300r is poor...
having build with it and had my hands on it for an extended period of time i'm not sure where you heard this. the quality of this case is excellent. it could have a few more zip tie-down points and a little more room for cable management but otherwise this is an excellent case in every respect.
I'm not sure there is such a thing as a poorly built corsair case.
