Very very good work and it is easy to tell that this was a professional. I like how he used bolts rather than push pins which is what I personally do my self. Mounting a socket A cooler that weighed 572g (copper) onto a Asus P5N-SLI to cool the NP wasn't easy then I had to get very long bolts to mount it. It is now gone but did some modding on my GA-MA790x-DS4 to ware both NB and SB are bolt mounted. Yesterday I gave the sli hack a try with my two 9800gt 1gb editions and got sli working with out issue.
