I had an OCZ SilentXtreme 800W PSU when i 1st got this system. A mate of mine did the cables and i must say did a cracking job on it, was really neat imo, al post a pic soon.
But that PSU died and is getting RMAed, so i bought a WinPower and the cables on it are really short, there tidy just not hidden, if that makes sence lol.
What clocks yours Q6600 at and temps?
edit, heres a pic of my setup now, this PSU is hopefully just a temporary 1 untill i get my SilentXtream back or i got a modular. Plus this WinPower makes quite an anoying high pitch sound lol
As you can see the 8-pin (i think its the 12v) cable ONLY JUST reaches, i mean only just lol, with my OCZ i could thread it around the case so it was hidden, the wires show and are ugly, no wrap around them, i think i might drill an hole next to the PSU and thread the lot through to the back, that will get rid of the big horrible power cable.
