Should a waterblock ideally be in contact with ground or not? (ie. the standoffs or screws that make contact with it should be in contact with the soldered holes)

On my Leadtek GF4 card, there's a small spring on the back which makes contact with the heatsink grounding it. As is there on some Matrox graphics cards, which have a small wire connecting the HS to ground.

With mixed metal blocks, (Swiftech and DTWW) should the block touch ground or be completely insulated?

Would the water itself provide a ground path?

And what would be the ideal situation amongst the above in order to minimise any potential difference across the copper/aluminium?
