On a slightly different note, how does one remove the top cover to get at the engine? Is it a simple four screws like the cover on the underside? And is there any functional reason for the top cover? In other words, once removed, is there any non-cosmetic reason to put it back?

I realize most MB owners probably never (or almost never) lift the hood, but I suspect Crossfire owners are going to be more likely on average to want to get in there and check things out.

Cheers,
