I have an Inspiron 660 and I'm going to buy and MSI R9 270x graphics card. I want to know of this is going to fit. I have the power supply and the cooling to do it, I just need to know if it will fit. I have another case if it won't, but don't want to change unless i have to. P.S. How much of a hassle is it to switch cases? Taking everything out and putting it back in sounds kind time consuming. (I would have help doing it so knowledge isn't a problem)...
