I have never built one before but I do plan on building my next pc with something legit (i7 processor or whatever is out in a year or so).

I have this pos dell vostro 200 that I replaced the motherboard and processor on. We had a monster sized pc my fiance's bro built for her a few years back and the vostro was a slim case, so I made a Frankenstein and got the "best of both worlds" until we can afford something better. Gigabyte motherboard, 4 gigs of ram (32 bit windows), and went from 2.4 pentium dual core to 3.2ghz pentium d.
