Ill explain why: The flex bay or motherboard side, has to have fan mounts purchase to mount fans. When you do this, the fan sits into the accessory but it is not touching the front of the case. Basically you have a small gap between the fan front and the front mesh grille. The PSU side fans have holes for them, but the mount right up against the front of the case. To keep things uniform, I ordered the mounts pictured above. These are the mounts that are attached to the HDD cage also. It is nice that you can purchase these seperately instead of buying more HDD cages just for fan mounts.
Yep same here, I'm kinda thinking over between the ST10 and the T10. But I'm also considering going with the Storm Trooper and getting another gtx 670 a Sound blaster Z and WD 2TB green with money saved.
