Trying to decide on a case but I have been told that the one solid side panel and the top is a funk brownish grey / pewter color but it has an additional air-guide fan on the top (bonus). for a total of 4 fans as opposed to 3. I would think the top blowhole is one less mod that would need to be made and just deal with the funky side and top color. It also has a side window. Putting a P4 3.06
