I would stay away from the Thermaltake Commander MS-I. I have the snow version (not that the colour matters). The build quality is poor, when removing the top front grills the plastic pins or whatever they are called that hold them in place and have to be pressed to remove broke. 2 out of 6 broke, with minimal pressure on them. I was extremely careful to exert as little force as possible to remove them because they looked flimsy from the start. In addition, the airflow is not so great and you will likely be unable to mount a top fan (the ram slots get in the way) unless it is one of the thin ones (12-15mm wide). The case fan is really loud and spins really fast even when it is not necessary (that is easily fixable, at least) and the case does not dampen noise at all.
In short: I would strongly advise you not to get the Commander MS-I, especially if you intend to overclock at all.
