It would have an impact on the positive/negative air pressure - but the level of impact would depend on what fans you are you using and where you plan to move the HDD cage etc.
Are you using a stock CPU cooler or an after-market cooler that can be orientated to exhaust to the top?
It would be a bigger impact if you didn't have a top exhaust fan and were just relying on Front>Rear flow
If you plan to move/remove the HDD cage the effectiveness of the front intake will be diminished if you plan on using mesh.
Also does your video card have exhaust out the back, or 'dump in the case' cooling?
