I used these.

If you want to go dual loop with single reservoir I`d recommend the dual DDC pump top/res combo. Since those pics were taken I`ve mounted the two DDC pumps on one of these and found it to be much better. Just had a quick look, but OCUK don`t seem to have any in stock though.
They slot into the drive bays and take up much less space than the way I had originally mounted them in the pic. There is a slight snag in that the small tabs sticking into the drive bays need to be cut out to enable it to slide in, but it`s easily done.
Depending on where you locate your radiator, you might only get 4 screws into solid material but that`s enough to keep it in place. I left all the original perforations in place and used a holesaw to remove a suitable amount of the bottom of the case.
You`ll need some small drill bits to drill out the rivets and radiator mounting holes, but sounds like you`ve got the rest covered.

If you`re cutting a hole in the shelf for tube routing, some rubber blowhole trim tidies the edge up nicely.
As far as fans go I used Apache`s with a bigNG fan controller and you can barely hear them. I`ve had Yate Loon`s in the past and they`ve also been good, and are a bit cheaper too.
Hope it all goes well for you.
