For simplicity's sake, I'd suggest going with the X-Res 140. That does indeed come with a mounting bracket, and it actually decouples the pump to make it nearly silent. Pretty rad setup. Then just grab a D5 vario (very important that you get a vario, it has a higher setting with much better pressure/flow than standard D5s) of your choice. Could get the Aquacomputer if you are going the Aquaero route.
I was thinking of just going with EK XTX rads. I was looking at the Aquacool Vario pump. Only thing with these is that I wish I could cover the pump somehow to give it a cleaner look. Also, in terms of accessory wiring do I have to worry about sleeving SATA cables, pump cables, etc. or can they be hidden properly as to not be shown. I know that this can probably be done with the pump, but I don't know about SATA connections.
