do you even know it can fit in your case
it should fit; it's a small card
I'm more worried if he has the right slot
also, Randomness, I chose the R7 250X because it's very low heat output, the GTX might not have enough breathing room in a small chassis (which is what I'm assuming he's dealing with)
though it does require a 6 pin power line from the PSU so that's probably a problem too
