Needless to say, my BIOS boot time takes longer than booting into windows
With all this crammed into this midsized tower, all PCI slots are filled i believe if not then there is no way i would be able to add anything else. My temps stay extremely cooled just by fans, played crysis 2, diablo 3, battlefield 3 all maxed settings and never once hit any high temps on anything.
