Something loose doesn't mean it has to be rattling around. For example: Take a component that has two legs connecting it to a PCB. If one leg came loose, the component would still be secure, but the leg could make intermittent contact.

It's probably got some reason for being there.
99% of PSUs have this. It's an air diverter. It's to prevent the intake air from shooting straight out of the back of the PSU and not cooling the components towards the front of the housing.

After reading around the internet I'm also starting to have just second thoughts that this Corsair CX600 PSU can even run this ATI R9 280 at full load.

I get other calculator sites saying with my set-up that 400W minimum, 500W+ = no sweat.
It's a 200W TDP card (non overclocked). 600W is actually overkill.

That's not entirely true. There are lower quality. The CX series are rated at continuous, not peak like some cheap PSUs. So to say that a better quality 550W is going to put out as much power as a CX600 is absolute B.S.

The only thing you're missing out on is the temperature rating. A higher quality PSU, like an HXi, AX or AXi series, for example, is rated to output maximum power continuously at 50C. The CX is only rated to output continuously at 30C. What that means is that the CX600 may not be able to output 600W continuously if your temperatures exceed 30C. So then the question is: Are your ambient temperatures greater than 30C?

That PSU would work too. Again: It's only one graphics card rated at 200W TDP.
