Can I change cases to a non-PC Specialist one?

I bought my PC nearly 2 years ago from here but it's a standard case with only one rear exhaust fan and no intakes, nor vents to allow for more fans to be added.

As a result I want to seriously upgrade my GPU and need a case with ample air flow so I'm going for a large tower Corsair case.

Should I be able to take apart my current model OK and transfer everything including the I/O shield? The PCS case is a standard Black Enigma Case, if that matters.

Thanks!

It would be fine, you need to check your motberboard is compatible to the case you are selecting.
