I bought my computer in '07 (I know, I know... but hey, I don't give a shit).
Came with Windows XP Home, AMD Athlon 64, 1 gig of RAM, 120 GB hard drive, 512 MB nvidia graphics card, and some shitty 5.1 sound card, and a 19" widescreen. Really all I've ever done with it is swap out the RAM with 4 gigs and voila. $600.
Owned for about 2 years and formatted once. Other'n that no problems. But hey, I also don't flood it with 10,000 MP3s I never listen to and 20 gigs of porn I never watch.
Also got one uh 'dem dere Mac Minis for $700. I don't play favourites.
