Yes it'll fit. The question is though will it fit while its in the case?
That was my other worry, as my current case is pretty small and didn't fit the 770 as the HDD rack gets in the way of it. I feared as much when I bought the thing, so I ordered a new case along with it, a Corsair Graphite Series 230T ATX, which should arrive in a couple of days. I compared the dimensions of the two cases and the corsair is a lot bigger, and it's also built for gaming computers so I'd imagine they build those things so there's enough room in them to hold just about anything, right?
