Here is a Modded Coolermaster NR200 bottom panel.
This allows you to run a triple slot GPU by using the fans on the bottom of the case with extended case feet to accommodate the fans.
  I have also removed the metal material that covers the fans venting up, so it gets much more air flow now and use the magnetic filter on the top instead of the bottom.
Just run the fan headers through an unused PCI slot to your motherboard. 
Comes with 2 Artic PWM 120 mm fans and magnetic filter as shown in ad pictures. 

Ships next business day.
Thanks for looking.
