asus gtx 750 ti can fit

i think so if you move the hdd slightly above, but if you are not sure, use a tape, the gpu will have its length in its specs and then check if the box has enough

[strike]note: that board is h81, which has pcie 2.0 where as your graphics card is pcie 3.0; it'll work, but perhaps you should consider a cheaper card[/strike]

Edit: removed incorrect sentence
