Sunday update:
I've spent some time tonight on cable management. There's nothing worse IMHO than a really nice system spoilt by masses of cables - unfortunately the more complex your rig and the more parts you introduce, the mores cables it will have - so management is very important. It not only looks good, it helps with the airflow, and also makes the job of replacing components easier next time round.
This system is reasonably complex - it has the GT to consider, plus the waterchill system so there are cables galore - and when you introduce two optical drives, two Sata drives and a powerful gpu you have your work cut out.
I've used cable ties where appropriate on the reverse side of the chassis and I will route some cables behind the motherboard. I will try and bind the sata cables and the power/hd/led and reset wires have been braided, along with the USB cables. It's pretty tidy all things considered.
During the week I will be replacing the Vantec Stealth fans with some Silenx fans, both in 80mm and 120mm flavours. I want this system as silent as possible. All things considered, apart from the replacement front panel, its virtually ready for my FX53.
