Too each their own I suppose. I wasn't a big fan of the wavemaster.
First thing that happened when I got it out of the box was that I opened it and cut myself within a minute of playing inside. Coolermaster is usually good at either folding over the edges or deburring them, so maybe they've fixed this issue.
I also wasn't too fond of the top port. Anywhere I decided to put it, it was never convenient to get too. If I sat it at my right foot where I usually put my cases, then the desk covers it and I have to plug things in blindly. Then, if I put it on my desk I had to stand up to do anything. Front panels are the only place for this! I adapted by cutting off the door, putting an 80mm fan in there, and putting some metal mesh to keep the birds and rats out. I took an extra 4-port USB plate from my older motherboard and dremeled out holes in the front cover (the place where you put the filter media...on that door). Looks good, but it's a hellofa lot of work to get a $160 case to be usable again.
Then the fact that it still used screws to hold things in after falling in love with driverails.
I'm just different I suppose as, while I was happy it was much cheaper than the ATC's of late, I just didn't fall in love with it. Maybe it was the inside that just felt...well...uninspiring to work in. I love what many have been doing to this case and it's a great canvas for art. It's just that with items like Coolermaster's own stacker and the new Lian Li, there's not really a choice IMO. "IMO"...remember that, because that's all it is.
