bloody hell that is big... I think it may just fit in my case, if I don't have a harddrive in the slot the otherside of it. on secound thoughts, maybe take the harddrive cage out.
think how much it would block air flow though. It is a wall in the case...
edit: it would need a special motherboard, as there is a capacitor (or what ever those things are) about 1mm behind my card.
