I bought a Fractal R4 earlier this week from Newegg. When I took it out of the box, I was surprised to see that there was some sort of deformity in the top panel that kept it from sitting flush. The rear fan mount bows out; if you press it, it will bow right back up. If you press inward toward the middle fan mount, as you would in picking up the case, the middle fan mount bows out, but it can be pushed back down. I called Fractal's tech support number and they said they've never heard of anything like this. I don't know how much I believe that, though. Do any of you with the R4 have a similar problem? I'm trying to determine if this is worth exchanging the case over. I'm satisfied with it otherwise.
