Mine does this and it's a V2 as well.
Good to know mine isn't the only one!
My front panel is hard to unclip.
Same here but I don't really see much reason to unclip it often
That was something everyone thought would be fixed on the v2 mate. If my clips do break, im gonna do a mod with a few small magnets to hold it in place. Seen it on another forum so ill need to dig it out again.
The clips do seem very sturdy, no sign of them breaking it is just the rattling that is annoying.
For a temp fix I have put a little bit of foam in each corner on the top filter next to the clips and that has cured it.
I have also emailed Phanteks to find out what they will do to fix the problem. I don't really expect an annoying rattle from a ~£200 case!
