I got the NB block to fit by not bolting it down to the mobo. It was fiderly but i did 2 mounts at a time in a digaonly, one is at an angle. The other issue i found one bolt was longer than the other by a mile. QC is needed loads, base of block was scratched loads as well. Meh it's er, it fitted and didnt leak all night.

Off now to get it back up and running now leak test is done. Hope she works still
