I ended up using about 45' of the cheap PET sleeving. Also some techflex Clean Cut, maybe about 20'. I used the Clean Cut for everything that I couldn't get the PET around. That means the front panel USB and the 6-pin PCI-e wires that have 2 wires coming out of the connector (the ones that adapt to the 8-pin configuration).
As for the rest of the front panel, I ended up taking out the audio and e-SATA cables (was never going to use them) and stashing the fan LED controller wires in the front bay (I replaced the LED fans with non-LED ones). So the USB and power/LED headers were the only ones I have plugged in.
Only thing wrong with the PET is that it's kinda see-through, as you can see with my SATA power cables. I actually kinda like the way it looks, though, just a hint of color. But that's personal taste.
Here's the links to the stuff I used:

If they have it in stock, I've heard the Murdermod kits are the best you can get.
