But I am also going to start youtube too so wouldnt i need a i7 for the video editing i will upgrade the graphics card i also wanted a quiet pc to one that doesn't scream when it starts heating up and would i need speakers if i have a soundcard? and should i go external on a wireless adapter or internal?
Not for Youtube. Pretty much any device you own can edit content for Youtube consumption. You can get an i7 for that purpose but it performs almost exactly the same as the i5 does. The i5 is cheaper and allows you to free up more of your budget to get a better GPU.
As far as being a quiet PC the Fractal R4 is one of the best cases around for that as it has lots of sound dampening panels and has room for lots of fans. You can always add the fans in as you need them. As far as speakers go don't get cheap ones like the junk ones that Logitech sells for $20. Save some money by using the ones built into your monitor, then get some better ones later on like the Audioengine A2/A5s..
