I did not want to modify the clean lines of the G4 case...
And so, with a little research planing and rumaging, I came up with this subtle but effective solution of my own.

First I removed the speaker, and speaker housing (metal & plastic cover)
Then shaped some steel mesh to fit the hole and put a dab of silicone to hold it in place. |
This now acts as an air intake... It blends well with the case design and works well. |
| Here we have the rear. This is where it got more involving... |
| First off I needed to cut and grind away the vents to the size of the total width of the dominator fan-set (Marked in red) . Then I drilled out 2 holes (marked in blue) for screws I used to fasten the fan to the rear of the case. |

  |
| Using some more mesh i shaped a grill for the rear of the case where I installed my fans by screwing and snadwiching the grill in between the case and the fan frame. |
| to create the shroud I shaped some sheet metal into a "U" shape or "hood" to fit over the heat sink making something like a tunnel around the heat sink by pushing in the "hoods" edges in between the first and last 2 fins of the heatsink. |
 |
| I found some (real) duct tape and used it to extend the "tunnel" to the rear fan. |
  |
| I used sticky velcro strips to better hold the front fan in place. This also makes it (semi) removable and reduces vibration a little. |
 |
| To increase airflow and make space for the front fan, I discarded the power supply's bracket/support. I realised that the depth of the CD bracket didn't give the fans much room Now theres about 1" between the front of the fans and the back of the DVDR. |
I also cut the stamped metal from the front of the large Case fan. This now forces all "fresh" and cool air in from the bottom of the case |
 |
| To finish up , I carefully tucked wires and put sleeving on the rest to clean up the inside. |
