Since I removed the middle fan bracket to make more room for PSU and water pump and I don't want to lose the air flow for the HDD and PSU,
so I'm going to move the middle intake fan to the front of the HDD cradle.
To install a fan right in here, between the grill and the HDD bracket.
However the bracket is obstruting the installation, its need to be removed.
Oh..the green tape is to help to hold the bracket in place for a photo, forgot to take a pic before I removed it.
Well the cross bars is getting in the way.....nahhh don't worry about the dust on the fan, it's an old fan sitting in my gargage collecting dust.
Tapped some holes on the back of the mobo tray, these holes (red dots) will be use the the screws to hold the cable clips.
