also .. if you have spare fans at home ( broken possibly ) break them to keep the outer plastic piece and glue it yo your fan like this. it adds a little extra pull/push effect ( i tapped mine with electric tape ...works wonder )
fan <--- windtunnel <--- radiator <--- windtunnel <---- fan
fan <--- windtunnel <--- radiator ---> windtunnel ----> fan
(<--) air current = push/pull configuration
according to certain "tests" push/pull is better ... my personal experience says it depends on the case air flow best configuration ( my moded nine hundred has 1 output of air ( the top huge fan ))
The first example IS push/pull as the term is referring to the air being pushed by
1st fan --> rad --> 2nd fan(this fan is pulling the air being pushed by the 1st).
You can do push/pull in either direction just don't mix them up like the second example where you would basically be blowing all air(cool or warm) away from your radiator while the 2 fans fight for what little air could be sucked in from cracks and crevices where they meet the radiator. Not going to be very impressed by that I'm sure. Similar scenario if they were both blowing inwards -> r <- as your heat dissipation would be limited to how much of the turbulent air pocket you'd be creating could escape out of the same cracks and crevices.....and that's all if you at least had matching fans...might get away with not frying your cpu if one fan was stronger but you'd beat the hell out of the weaker fan.
The shrouds(wind tunnels) are definitely a good idea though.

Hey if I can reach in the HAF 932 well enough to be staring at 28c at 4.374 mhz while I'm writing this I can't imagine it'd be impossible. =)
If you're sticking on some quality fans in push pull they're going to be creating a pretty strong current to where you might not actually have to "reach" the front to still get air from it. Having a shroud or two can make the reach a little longer, heh. My H70 rad is maybe only an inch or so in from the edge of the 5.25" bay but it's pretty heavy(especially with 38mm 3k Ultra Kaze's on either end and shrouds.
I haven't really figured a proper way to mount it other than catching one of the screws around a zip tie and securing it to the side. That's how I had it for a while but really it's not even needed if the base is oriented to allow the rad to "sit" on the bottom of the 5.25" bays...I think everybody has a nice solid piece there.
Might not work if you have giant ram heatsinks with fans on top of them but i can still fit a ram cooler on my ram and have enough tubing to go around it and still reach the bay.

I just buy reinforced disks...don't bother with diamond...expensive and goes fast...I wouldn't use weak ones either though make sure they're reinforced metal...don't want little pieces of metal traveling your way at 35k rpm lol.
