I have noticed that the front section, which is the entire portion from the usb sockets all the way to the intake fan vent at the front, is not fitting securely to the rest of the chassis. You can clearly see this on the side and there is quite a large gap. I suspect that I have taken it off (to clean) and maybe some fittings have come off and that means when it snaps back into place it's not as securely as before.

I have contacted antec support twice, once regarding spare parts, as I was curious if I could just purchase the front section (or fittings) but rather than specifically show me if that was possible, they merely referred me to the spare parts section of their website, but I cannot see this front section anywhere, it seems to be rails, drive bays etc.
The second time I have contacted for warranty support they have never answered.

My questions are: is the front section usually secured down with some bolts screws or something or is it supposed to just click into place when you press it into the chassis (no other fittings necessary)
Is it normal to have a gap of several mm's between the front section and rest of the chassis on the side?
If it isn't normal and the front section is indeed warped/damaged can I get a replacement front section?

I wanted to provide photos so you could see what I mean... but cannot see how to attach?? hopefully you understand what I mean anyway.
