I have a Hiper 580 and an Antec p180. Yeah, I wouldn't recommend it to anyone, but I finally got it to fit inside and once that's done, the modular cabling is actually quite nice.

I've managed to snake one of the molex leads past the fan in the lower part and I was wondering. If I have four hard drives, could I connect them all to the same cable or should I try to get another cable in there?

I would prefer to just use that one cable so that it would be one less modular cable coming out of the psu, but if it's a bad idea, then I guess I have to bring another one in there. Thanks

technically 1 cable would work. so try it.
