case compatability to mobos

Hi I am thinking of building a computer in the near future. I think I am going to order this mobo, and this case
I look at the back of the mobo and see the ps2 things, an ethernet port 6 things that look like a sound card. Then I look at the back of the case and it dosent seem to have all the holes for the back of the mobo. Can anyone tell me if this will work? If not point out a case that will work with a 450 watt power supply. Thanks

all boxed mobo's come with a I/O port (if thats what it's called) so that you can pop the one off the case and put that one on. So dont worry about that unless it's just the mobo alone.
