On my hardrive I have now idea. I have two of them. One is 120, and the other 40. The hardrive works fine, I am just not sure to buy the AMD X2 3800 or the AMD 4000. I just purchase kinston 1 gig ddr2 ram? Is that good, or should I stay with coisar? I need some feed back on what type of mobo and vga card i should purchase?
