Since I had to mod my SB for my EVGA 680i and 8800 gtx (SB screw hits card) I got hardware at local store (Lowe's) and made my own standoffs for both NB and SB.
Parts are 1/4"nylon spacers, and 3/4" 4-40 screws and nuts. I used the nylon spring bushings that come with the chipset blocks and slid it down inside the top of the spacer.
The combination of the nut, nylon spacer and nylon bushing create the PERFECT distance needed (just under 10cm). The mounting plate rests a hair line above the bushing (which acts as a soft washer with "some" compression for tightening tolerance), when the copper block rests on the chipset.
I ran a nut all the way down on the screw of the SB block where it comes up under the GFX card to shorten it the thickness of the nut, so that when it is run up through the mobo from the backside, it and the top nut clear the gfx card by 3/32".
I would have rested the nylon bushing on the mobo but I wanted the screw to be bolted to the mobo (per original mounting application) so it would let me do maintenance on the waterblock. FYI, I am told that the kit that Swiftech is making for these has a threaded standoff which "should" act to secure the mounting screw to the mobo
I know I could have reversed the screw, but again, I wanted the screw to be bolted to the mobo. (no need to remove mobo to reattach the mounting hardware)
The screws are identical thread as what's shipped with the MCW30 so the sweet lil black finger nuts can be used, but the nuts that come with the new screws are larger which is better for stability when mounting to the mobo. Any force on the wb causes the mobo to flex and not the waterblock, so this is very solid. I also used the thin fiber washers that came with the wb's.
So, cheap, effective and hardware from your local store. (I painted the nylon spacers black
)
