a couple of things I noticed is:
For your stated use, the CPU's stock cooler will be fine, so you don't need the CM Hyper 212.
Do you need OS, monitor(s)? I notice their absence in you parts list.
Also, you chose an ATX MB and an ATX mid tower case. you could save some money and space with mATX components or even ITX.
Your video card is pretty weak, though your stated needs don't require much. One thing to consider is whether you might use dual monitors. My son multi-tasks a lot while he does homework. uses one screen to look up stuff on internet and has MSWord with his current assignment open on the other. so you might consider upgrading your video card to something with dual DVI outs and buying 2 monitors. If not you can save some $ by selecting one with onboard video (HD 42xx series or something).
Also, would you consider an Intel mb/cpu solution? the LGA 1155 Sandy Bridge (SB) is the new in thing. even the lowest priced SB CPU is as powerful as the AMD CPU you picked out. I'm not saying AMD is a bad CPU for your purpose, just that SB is the current technology that's out right now.
just food for thought. Please repost with the build advice form, so we can make some solid recommendations.
