I decided to move my bottom rad below the fans, since I felt that would probably be better off. However, there's a bit of a snag I've got to fix... Undecided on how, as I'd really like to avoid cutting into the case with tools. That would mean nasty bare metal, even if it's in a barely-if-ever seen spot...
Oh, the problem? Yeah, looks like this.
That said, I disassembled and reassembled my GTX 680s. They were a bit overdue an inspection after a spillage accident, so I checked that they looked fine and all. They were, far as I could tell.
Finally, here's a lil' shot of the left side of the HAF XB. Well, the components seen through that when the panel is off, anyway.
