should be ok, except the no-name brand PSU. for your build you won't need 500W, so see if you can get the Sea Sonic 300 or 350W supply. It's a high quality supply
If its just for browsing, the onboard video will be just fine. You might even do better with a Linux distro.
you might want to up to 4 gb, but its not NEEDED for just web browsing and light office work
