Only problems with the 650D and 600T being the gpu temperatures. If you're prepared to do something about them (e.g. single HDD bay with aftermarket 200mm fan) then fair enough. Keep 'em stock and your gpus will suffer. The stock fans on both cases barely move enough air for you to feel it on your fingers.
I have a friend with AMD Phenom II X6 1055T and it runs at 15C with just the 2 fans that came with the H100.
Oh what!! if you had said you had £200 to spend I would have gone straight for that case for you.
A H80 etc is a much simpler fit and theres plenty of pics around of the FT02 with these things fitted, looks very nice.
