The build looks good to me too.
If you plan on ripping your DVD's to the hard drive for instant access, you may want a larger hard drive though. The gigabytes just disappear when you start ripping video.
Another small suggestion is to look at the newer GA-MA78GPM-DS2H
for a little more $$$.
It's basically the same board as the GA-MA78GM-S2H, but it comes with dedicated 128MB DDR3 SidePort memory for the video.
