Overall, I was pleased with the features as well as the cooling performance. It certainly has the potential and the look to serve as an HTPC rather than a gaming chassis. I say this because In Win's website has this case classified as a "gaming" chassis. I just can't see how though. It might just be me, but for one, 300 watts isn't going to cut it in my book. Even for the average gamer a quality 400W would be the minimum, in my opinion. Second, size is definitely an issue, limiting the form factor to m-ATX standards can be dealt with but ruling out most aftermarket coolers is another thing. You would have to look for coolers that are about the same size as Intel's or AMD's stock cooler or look for a small design heatsink. Though it may be described as a gaming chassis, it can still be the perfect solution for an HTPC or an average home or office computer.
