If you look closely I left a small lip on the rear side of the cut/case. Wasn't obvious at the time but when I went to attach the radiator I saw it and realised it wouldn't quite be level if I left it. Had to go back and cut it off but worked out in the end There was a really good post on Martins liquid lab (link) a few months back exploring galvanic corrosion in depth. Shed a lot of light on the topic for me, and to drive it home there are pics of corroded blocks. Worth a read if you're curious Starting to plan a small PCCG order as the build progresses, any ram aficionados about? Based on my board and reading up so far I've been thinking of grabbing the*Corsair Dominator 32GB (4x8GB) DDR3 sticks. Prod code is*CMP32GX3M4X1600C10 if the name is unclear. 32GB is a little overkill, granted, but will provide scalability for future anyway. Any thoughts? Any strong reasons against?
