Not that I am totally opposed to getting a CM case, I just think they are somewhat tacky.
I prefer something like:
1) Fractal Design R4 Windowed Titanium Gray for $99.99
2) Corsair 650D for $152.99
3) Silverstone Raven RV-03 for $144.00
There are other cases in that price range that are good, but I usually prefer a bit more subdued case. The ones I have listed here are all well made. They are not technically full towers, but they have plenty of room for what you would possibly throw in them. (and would fit the previously supplied build +)
