Ok so i plan to buy a Corsair 900D but with the current build i am working out for it, the motherboard that will be inside it (ASUS Prime Z270-AR) has no usb 2.0 ports but it does have 4 front usb 3.0 ports so i was wondering whether i'd be able to modify the case swapping the 4 usb 2.0 ports for 3.0 ports and then either covering up the potential holes left from the original 2 usb3.0 ports or using them for something else.
Would this be possible to do?
