silverstone FT01 solution required

I am planning on buying the Silverstone FT01 as my next case, but there is one problem. the front bottom 120mm fan (the only fresh supply of cool air for the gpu) will be blocked since i do have 5 HDD's. Because of this my gpu will be running warmer than i would like it to. the one thing i have considered so far is to get silverstone's CFP51 5.25 bay conversion kit, moving 4 of my drives up to it to clear out the bottom fan.

the one thing im curious is how this would effect the airflow of this case. it clearly has a very specific layout and plan. I wonder if this would cause any problems or reduce airflow efficiency.

if anyone that has a FT01 or has reviewed one or has a great understanding of case airflow (keep in mind its a positive pressure style) could give me any help on this matter it would be greatly appreciated

thanks
