Whoa easy dude, I have never built a computer so my knowledge is somewhat limited. My friend has built many of them though and I unfortunately get stuck listening to him rambling on about computer jargon occasionally lol. I was just saying this because I thought getting all your own parts and putting in the time to put it together would be about the same as buying one and adding on to it. On a side note; where do you get most of your computer parts from that are so much cheaper? I've gotten things off Tiger Direct before but I was wondering if theres somewhere else you get stuff from thats even cheaper?
