PC for my Grandma

Hey guys,

My grandpa wants to replace my grandma's PC, so instead of paying too much for lackluster hardware, I convinced him to let me build it. I wanted to see if you guys had any suggestions yourself. I'm merely looking for a most bang for your buck system, that can handle generally web browsing and emailing. After many revisions, here is the build I'm currently looking at:

I welcome all of your thoughts on the matter and am open to changing anything. I can't seem to get people to agree whether it's best to go Haswell or APU. After much reading I decided a dedicated graphics card would be necessary in the Intel build, but I'm still leaning towards it. Also, my grandpa is footing the bill and isn't concerned about cost, but I'd like to keep it on the cheap side. Above all else though, I want this to be the last system she ever has to buy. Let me know your thoughts, not use to building in the low end like this. 8)
