I have an extra Athlon 64 X2 6000+ CPU. I was investigating to see if I could use it to put together a basic home system for the girl friend. However in comparing it to this Dell $400 system,

in which I figure the processors are roughly equal in performance, I don't think I can put together anything cheaper using Newegg components. The kicker is the $100 windows 7 OEM price. I wouldn't build a new system without windows 7.
Can I be proven wrong?
I think it's possible but very difficult. Last November I managed to put together a system for $262 (after rebates and cash back). That's about $360 including the cost for an oem license of 7 (if you look around you can find it slightly cheaper; I think zipzoomfly has it for $87 after rebate, fs).
If I were attempting to match a dell build it would probably be harder, but I was only going for good enough.
The specs are a 785 gigabyte mobo and x2 240 combo from newegg, 2x1 and 2x512 ddr2 used from craigslist, a corsair 400w power supply from newegg, CM matx case from microcenter, and WD 640 aals from newegg (black friday sale). While I could probably do somewhat better with dell, I doubt the difference would be significant, and when building I get to choose exactly what parts go in. Having to buy a windows license definitely hurts but you may be able to get a copy cheaper if you are a student or your company has a special deal with microsoft.
Beating the outlet, however, is probably impossible, especially when they have coupons available (such as the recent %15 off coupon, which I believe has expired).
If you want to get the absolute cheapest option available, then a prebuilt is probably a better option. However, if you're willing to spend slightly more and have the patience to wait for deals (and be flexible with what you want), you can come pretty close.
And if you're fortunate enough to have a Frys or Microcenter nearby, then it should be that much easier. Frys routinely has motherboard/cpu bundles that go for $100 or less for entry level. Microcenter has been running a combo promotion where you can get bundle specific processors with a compatible mobo and take $30 off (this has ranged from $25 to $50). No doubt this is more hassle then buying a prebuilt, but I enjoy watching the deals and seeing how low I can bring the cost of a self built computer.
