OCC has published a new review on the Thermaltake Matrix

So in the end, would I recommend this case? Not as a case for an extreme enthusiast, but as a standard desktop case or even as an HTPC case, the Matrix is well suited for the job. I would however, love to see Thermaltake's next stab at this design. I want to see better temps but keep the side access option, that was a nice touch. For now, as it sits without the additional optional cooling features, the case was outperformed by the comparison cases. At less than $50, you get what the case comes with. As a performance PC case, the Matrix is ill suited in stock trim, but add the optional cooling features to reduce component temperatures and you have a classy looking mid tower case.
