Good case with a few small issues

Great case with a few nitpicks, mostly do with screws. The thumb screws on the back are either poorly threaded or poorly positioned. The fan screws are also not quite properly sized for the fan brackets, making it incredibly difficult to reposition/replace the fans. Finally, the mesh on top is a bit fragile, mine had some splits/breaks just from handling. I'd recommend taking the top mesh filter off entirely and setting it aside until the case is in it's final position.

Excellent for the $$$

This is a very nice case. Easy to work in and well built. The only 1 thing I'd change though it's not that big of a deal is one more case fan up front. I usually set my case fans at a steady 500-600 rpm which makes them nearly silent. This usually gives my rig generous air flow with no heat issues.
