I have build 3 PCs with Apevia cases. I used to like them a lot and there is still not much wrong with them. THeir tech support was great when I tried to customize one case and broke a part - they just sent me a replacement for free (was a small piece of plastic covering a LED light).
However, my last, slightly bigger computer I used a case from Fractal Design. Even though I had a few quibbles with some of the stuff in the case, I'm seriously considering another Fractal Design case for my next build - their R4 case has fixed some of the quibbles I had with the R3.
But as the previous guy said, most cases are just fine and you should go with your personal preference.
