Here's my solution for the SB:



I bought an Enzotech CNB-S1L from Petra's and 'Dremelled' it (new verb). Was a PITA to get those holes at 42mm separation, and also had to chop the end off one of the mounts as it was hitting that cap - but it seems to work ok.

The motherboard is a Gigabyte GA-X38-DQ6.

I'm also using the MCW30 on the NB and the Apogee GTX with copper top on the CPU - seems to be a popular combo
