Ah yes, that was truly one of the most awesome mods I've ever seen done to the RVZ02. Best part is other than the mesh grille, it looks stock - I'm a fan of putting mods in an unassuming case.
As for ITX versions of cards, perhaps we can guess-estimate by comparing the release dates of the 970 and the 970 ITX versions. I'd rather not butcher my case with my shaky, shaky hands in an attempt to squeeze an HDD and a full-sized graphics card, but if it takes too long, I just might.
Any luck replacing the front LEDs?
