Still waiting on my mobo and other parts but i decided to try and tackle the issue of cable management with the psu, after removing the top mounting bracket I found that at least for my sf600 it could be rotated 90 degrees and mounted to the front face of the case (needed to drill 2 3mm holes), letting me route all my cabling to the right instead of down directly towards the motherboard, this removes the problem of the fan hitting the psu cables and should allow for very neat cabling. Need to see what its like with the mobo and ram installed but because of the shape of the psu not being square there should be enough room for everything.
