Nice looking case! The thing I've found with various cases when shopping online is that I really don't know until I open the box what kind of screw set they provide. Some case manufacturers put "built-in" standoffs for mATX and provide extra standoff for standard ATX motherboards. I have also seen new motherboard's accessory bags come with extra standoffs in case they are needed. So, where the holes line up with the missing standoffs, you probably have holes in the case to manually add standoffs... question is, can you find extras in you NZXT accessories, or your motherboard screw set? Yes, you can run your computer without the missing standoffs, it's just that you have to be very very careful when inserting a video card or the USB...
