A little while back, AnandTech took a look at the Atop Translucent X2, the first translucent case to make its way into our labs. Unfortunately, we found that case a poor choice for anyone interested in anything beyond the looks of their case.

But Atop has been in the business for quite a while, with OEM wins such as DTK. That doesn't just happen as a result of pure luck, so they must be doing something right.

Today we take a look at the second Atop case to run through our gauntlet of tests. That case is the AT900, which is a far more traditional model than the Translucent X2.
