Hey everybody. I have been prowling around this forum for awhile getting a major education. This is my first attempt at building any kind of PC. I have a few things picked out and would like input if what I have chosen will work for what I need and need further advice on the remaining items. Here is what I have so far.

MOBO
From what I have read the AMD 785 chipset deals with video better than Intel. I am going for onboard video so that I can avoid added heat from a discrete video card and the possibility of interference with HDD's. I also like the mATX (smaller board in a large case for better airflow?)

RAM
Hope this set works. Is there cheaper, better or do I need more or less?

AUDIO
I know, who does PCI sound cards right? I have a Denon receiver that decodes hidef audio from bitstream. This seems to be the only way to get bitstream out.

What I cannot decide on is a CPU and PSU.
Any suggestions on a CPU that will get the job done and then some?
And about all I know about the PSU is that it should be modular.

Thanks for any help.

Hi obsidian86. Thanks for the case suggestion. I was really on the fence with that.
But on the RAM you suggested. First off I wasn't paying attention to voltages and now that I check up on the GB mobo it requires RAM at 1.5V. My first choice was at 1.8 (Yikes) and the Gskill you suggest is 1.6V. I cannot find a friggin single stick that is suggested by GB on their qualified vendors list. If I were to get ram at 1.6V would that play nice with the mobo or should I really look for 1.5V?

I'll look into the low power drives a little closer.
Thanks.

Allright then. I'll go with that ram.
Any ideas on a PSU and I think I am on my way.
