This doesn't apply to all cases, but the majority that come with fans I wouldn't expect the fans to last as long as good aftermarket fans. Even going with a name brand case several years back, I got a new Antec case. The supplied Antec fans were ok for awhile but only lasted maybe a year. I ended up replacing with Scythe fans. Especially on a case at that price. Usually 2 good quality 120mm fans cost the same as that whole case does, so if they last even 6mo to a year you're getting a deal. Better cases are more about design, features, rolled seams, access to hard drives, cable routing etc. A less expensive case is perfectly suitable.
