Why do you pick those parts out the spot? I assume you are buying from am manufacturer or you even'd it out to be in your budget.
Well and e7500 is alright, but if all you tell me is the general email and some videos online, you don't need much so yes it would work, i dont know about that video card though, onboard graphics would be fine as well if your not doing anything else, i used a compaq computer with i dont even know what onboard graphics but a pentium 4, 70gb hdd, 512 mb, and i browsed the internet, email, GAMING, watched anime/videos and i was fine, of course it was slow but it was decent. So i guess its the speed now you want to ask yourself, upgrade a little more and it'll run a little faster? (without including your internet prvoider & speed of course, since primarily how fast things would run off internet is also more on your internet.
