Will this motherboard fit in my tower and all the hardware?

I want to upgrade my pc to the cheapest am3 socket motherboard so I found the "BIOSTAR N68S3"

The link is here:

Now my pc is a hp a6683w and the product specification are here:

Now the question is will all the hardware(Including my Nvidia 9400gt in the PCi Express x16 slot) fit in the biostar motherboard with the tower/case without a problem?
