Surely it wouldn't work at all with the SG06? The fan is showing out the front because of the space - the blank front panel of the SG06 wouldn't allow you put the 120mm fan on at all...
As for the fans becing clean could it be because they are new?
I thought I saw a mod on an international forum with metal fame underneath the cover trimmed away to provide more room for a push pull combo. Can't find it now, so I might of been mistaken. Nearest I've seen is this
For rear fans I meant clean installation with the rear hole cutting. I wouldn't have the confidence to mod a case myself, so slightly envious of people with the skills and tools.

i see you have a antec fusion and you managed to squeeze a HD 4870 GS in there , Can i ask did you have any trouble getting the lid on with those 6 Pin connectors being on top of the GPU card , Im interested in a GTX 460 GS coupled up with a 650w TX Corsair PSU but am worried i wont be able to close the damn thing up
