I have a 500 gb external hard drive, another 500 gb on my laptop and probably 180-200 gb hdd that I'm planning on ripping from my old desktop so I'm going to keep on the cheap side and for now I plan on installing Windows using a USB so I don't need an optical (I barely use those things anymore) but I also have a DVD drive I can rip from my old desktop. Thanks for the vids, I'll be watching them over and over in anticipation as my parts ship in (by hopefully next Wednesday ?).

Are there any safety precautions you recommend for a first time builder? Things I should be careful about installing so I don't end up damaging expensive parts?
