So i'm planning to buy a NZXT H440 for my case, the thing is it has 7 expansion slots at the back, my question is simple, with a MSI Z97 Gaming 5 mobo, are the 7 expansion slots enough for 2 cards in sli and a wireless network adaptor in the pci x1 slot?, maybe the possibilities of a sound card as well (although thats probably never going to happen)
