Case side panel not shutting all the way.

[FirstTimebuilder777]

The right side panel on my case is not locking into place all the way, it can be shut but its slightly wobbly and one of the screws won't go in all the way. Could it be a wire or something else in the way. It doesn't seem to be bent at all but its making me crazy how it wont shut all the way. There is a space between the side panel and the front of the case but it is very small. I have tried several times to take it off and put it back on but it does not seem to be locking all the way into place. I dont think a wire could be blocking it but if it was would that be bad for my system? Should i stress about this or is it ok? Please let me know Thank you.
Here is the case though im not sure if it will help any http://www.ebay.com/itm/VIVO-ATX-Mid-Tower-Computer-Gaming-PC-Case-Black-Red-3-Fan-Mount-Dual-USB-3-0-/381324925709

I suspect its probably a minor defect. Could try the screws without the side panel on to see if the threads are ok on the screw or case. Also looking at this it has pices punched out that fall into the holes. Im assuming you have to somewhat slide the panel into place so all those punched out pieces fall into the holes... maybee one its sliding in place. Probably have to lay it on its side and get a flashlight.
