Hi, I recently bought this new Dell Optiplex 745 SFF computer off of my brother and I really need to upgrade this damn video card. I can't stand integrated. But since it is a Small Form Factor case, I am supposed to get an SFF video card. Well, I don't want one. So I was wondering if I can just modify the innards of the case and leave the door off and will it be fine to just use a normal non-low-profile Video Card in this case? It is PCI-E so if you know of any good cards for under $75 throw them at me, I just want to play The new Borderlands game. Thank you all.
