  1. Great Case for all your pc needs 5 Star Review

    (Submitted on 9th Dec 2014)

    I've had this case since about 3 months after release. I think this is one of the best cases of all time. It is very flexible as to what you can use it for. The only thing I would have changed is the height above the motherboard so either a thicker radiator or a push pull fan setup could be used.

  2. Totally Awesome Case 5 Star Review

    (Submitted on 18th Apr 2013)

    Last case you ever need
    Nothing out there compares to the flexibility and
    the features for configuring of any thing you can think of adding. Construction is high quality. I looked at this case for 6 months comparing to others.
