Sata cables are just covered by my hard drive ;). They go underneath the bottommost drive and around the bend to go back behind the drive tray. Couldn't get a good picture of them since my other cables are covering them. Not sure if this pic helps. (Also, the 'sandwich' for the fan is how a Noctua D14 normally is, nothing special to it.) With a little patience, I'm sure you'll be able to get it to your satisfaction.
As for another case, I'm partial to the 690II since it looks pretty good imo. I'd also like to point out that you should try and pick a case that looks good to you or at least has a good compromise between looks/cables. All the great cable management in the world will do nothing if you hate the look of your case. Just my 2 cents
