The 300 is a nice case. I am in the process of moving my system into my new 300 and so far I am very impressed. The quality is great, wire management is good and the cooling is top notch (I added 2x120mm intake fans to the included 120mm and 140mm exhaust fans). I would say that's pretty good for a case that was $60 with free shipping.
Edit: I just finished and my cpu idle temp dropped 5c and my gpu temp dropped 10c with the 300 vs my old case.
