Help with economy build

[Pastullio]

Hey guys, im looking to build something like below $400. Im very open to some cheap barebones deal. I just want something I can possibly throw a decent video card in at a later date and do some decent gaming. Ive got a decent hard drive to use, and will possibly use my old video card if need be. My old pc just died while I simultaneously got cut down to 3 days a week at work so I really need to cut a few corners but would love to keep some hope in it to be useful for a little while. Im also out of date with everything, last thing put together was an amd thunderbird? or something im very out of touch. I have no brand preference, just want some bang for my buck and I wouldnt be upset to spend even less than $400. I live in the US, have read other threads but im so out of date I cant really form any intelligent opinions on what to do. Id like to get this done asap since internet isnt being used and old lady is angry. Thanks, sorry for being such a tightwad too.

There you go all the major components you will need for a decent build, dual core processor, 4 gb of ddr2 ram, motherboard with decent onboard video, power supply and a sata hard drive. All you need is a case and this can all be had for around 250$ so if you wanted to get a decent vid card right away you could.

The Biostar 780G and the EA430 that an51r linked are fine.

Swap the rest for these:
X2 4850e (2.6GHz, 45W) $54 - faster, cooler, includes a basic heatsink/fan
G.Skill 2x2GB DDR2-800 $40 (free shipping)
WD6400AAKS $75 (about $25 more for 4 times the capacity & better performance)

And add this for some good gaming:
Sapphire 4830 $90AR
