Well does he NEED everything here or can he reuse a monitor?
Chaintech VNF4 Ultra-----$75
AMD A64 939 3200+-------$166
1GB Value RAM (corsair is best price usually) $75
Enermax 400W PSU------$65
Seagate 250GB SATA drive----$99
NEC ND3540A.....what you had
Use onboard sound
That leaves 250 for a monitor...if he can't reuse. If he can....yu can upgrade a couple partls slightly and still have money left over to send me for some pizza.
Use newegg.....if he has to buy a new monitor and SoundCard you will have to downgrade your 7800G to a 6800GS.
Get Corsair value ram 1Gb kit (512x2) it should be like $75-$80
with the 7800G you could have gotten the XFX, but you have to downgrde because you have budget of 1200, and wan a new monitor and Sound card....
Dont get a soundcard for more fps.....get it because you want slightly better sound. but know this SC and dell monitor is dropping your gpu from a 8(from 1-10) down to a 4.5(from 1-10) Maybe you can drop the Sound card and find a monitor for 250 and still be able to get th 7800GT
7800G is WELL worth the investment for serius gamer.....no joke, he dell 2005 is a grea monitor but i would ratrher have a beast machine and an alrightr monitor then beas monitor nd an alright machine.
Be careful, that 350W PS does NOT have dual 12v rails, so might not work for your components. This one is better, and is a great deal today at NewEgg: ENERMAX EG425P-VE SFMA 2.0 ATX12V 420W Power Supply http://www.newegg.com/Product/Product.asp?Item=N82E1681... Or consider a combo case & PS from Antec. I have this one: Antec PERFORMANCE TX1088AMG Gray Steel Server Computer Case 480W Power Supply - Retail $139+shipping, though you can go cheaper.
