DELL PRECISION 390

Any advice for a non gamer who just wants a high end office computer mostly for stock trading. I have a DELL 360 workstation now with a 2.8 P4. Would like to buy or build a computer that is not a HOT box very little noise and faster than what I have now. Building my own would be fun. DEll has USA support for the 390 workstation. I have used it and it was great very little wait time. Thank you for any advice.

Thank you for wanting to help.first thing is I want a tower low heat output and
quiet computer. My office is small and the room gets hot with the computer heat here in Arizona. Normally I will have two or three program running and researching stocks on the internet. no big number crunching software.Also all the other software running in the background such as anti virus. buying or building either way is ok not a problem.I just want the best bang for the dollar.Also waiting for the price cuts in July seems to be the smart thing to do.

Thank you for taking the time to help out. After researching each item on your list I felt that they were very smart choices. I have 3 old computer cases , but was sold on the idea of buying a new case after looking at the case you pick out. Same goes with the psu looks like a good place to put the money. As for the cpu that was also my pick. I feel that the Q6600 will put out just to much heat verus the E6600. I could be wrong. The price on the memory sure was right. The whole package is getting me gun-whole to get my order out. I will wait for the price cuts to put in the cpu order other than that it looks like it is a go. I have learned so much on tom's hardwaare and THANK YOU AGAIN.

I might suggest a Gx620 (dell).
They are very quiet, well built, cool...
