Deal hunting
I walked into a Best Buy today and ended up walking out with a pretty decent computer for ridiculously cheap. I haven't owned a pre-built system in years, prefer putting one together myself, but this was an impulse buy on a good deal. It's a Compaq SR1650NX with an AMD Athlon 64 3500+, 1GB RAM and a 250GB HD. The computer was on clearance and I managed to talk the manager into giving it to me for $350!
It also comes with Windows XP Media Center Edition, which is kind of neat. I'm currently trying to get rid of the bloatware that typically comes with these machines. I've been trying to get a Linux box for some time, so I'll be dual booting.
Edit: Lucky me, I managed to snag another deal. Just ordered an nVidia 7600GT GPU for $130... that's half price!
