in response to "whats the difference between the usb 3.0 front pannel. Like is it worth it if i'm not gonna be transfering alot of data?"
Nope, absolutely not! I've not found a use for my USB 3.0 ports yet (except for 2.0 devices). The time may come when you'll want that feature but, like I said, a USB 3.0 panel for a 5.25" bay can be a later purchase. I personally don't see the need yet.
in response to "also, how is the one you choose? is their good air flow?"
Very good airflow, cable management leaves a little to be desired but it can be done effectively - I actually like the case (price wasn't much of an issue when I purchased it)
